Cosmic Rays, Magnetic Fields and Climate Change

Boyd St, Norman, OK , scubabear ou. The Delle Phosphatic Member of the Deseret Limestone entered the oil window in the early Cretaceous during the Sevier orogeny based on modeling studies. Paleomagnetic results from central and western Utah indicate that the unit contains two chemical remanent magnetizations CRMs that reside in magnetite. Preliminary petrographic and geochemical studies indicate that orogenic type fluids have not altered these rocks. The age of the CRM is prior to the modeled time for organic matter maturation in central Utah to the east of the folds. A second younger CRM in western and central Utah is postfolding based on a regional fold test. This CRM is of Cretaceous age and the timing coincides with the oil window based on the thermal modeling. These results are consistent with a connection between organic matter maturation and remagnetization but also suggest that other burial diagenetic processes may also be involved in acquisition of CRMs. Permission is hereby granted to the author s of this abstract to reproduce and distribute it freely, for noncommercial purposes.

The one thing about ‘matching’ algorithms that dating sites don’t want you to know

By Aaron Smith and Maeve Duggan One in ten Americans have used an online dating site or mobile dating app themselves, and many people now know someone else who uses online dating or who has found a spouse or long-term partner via online dating. General public attitudes towards online dating have become much more positive in recent years, and social networking sites are now playing a prominent role when it comes to navigating and documenting romantic relationships.

Online dating is also relatively popular among the college-educated, as well as among urban and suburban residents.

Phil, many thanks for a focussed and convincing presentation. For readers who have not followed along closely, the main points are this: Cosmic rays are deflected by BOTH the Sun’s and Earth’s magnetic fields and there may also be variations in the incident cosmic ray background.

Top 10 Lies Told by Internet Daters By Greg Hodge Think you’re going to go see that thin, blonde, buxom woman you’ve been chatting with online when you meet her for drinks tonight? Think that “affluent man” who you’re about to join for an expensive dinner, will be able to pay for both of you? Running an exclusive online dating site myself, I can attest to the constant battle in working to maintain the integrity of online dating communities by weeding out disingenuous profiles — yes, surprise surprise!

More than half of them, actually. After reviewing how many people have had to be turned away from my site, BeautifulPeople. The study of 1, single men and women — all of whom belong to various leading mainstream dating communities — was conducted across the US and the UK by global research agency OpinionMatters. The results uncovered a shameful excess of dishonesty from people purportedly looking to find their one true match. Fifty-three percent of American people surveyed said they lied in their online dating profiles.

How in the world are you supposed to discover your TRUE match when what is being put out there isn’t true? It’s as if some online daters are not hoping to have a romantic evening but rather are preparing to do battle by jousting with their noses. Women lie more than men by nearly 10 percentage points!


In interracial and intercultural romances, color counts for less than ever. But when it comes to marital commitments, and even public displays of affection, barriers still remain. Interracial dating has increased dramatically About half of Americans have dated someone from a different racial group.

Introduction. Dinosaurs bring wonder to children and adults alike. That such great beasts once roamed the earth is hard to imagine. Even harder to imagine is that some dinosaurs such as Tyrannosaurus rex were probably giant killing machines (after the Fall, anyway). Of all the many questions related to dinosaurs, their disappearance from the earth is the most mysterious of all.

They believe OE theory and in the claimed processes of evolution, but maintain that the initial matter and scientific laws were brought into existence by God Gen 8. They would also take a figurative non-literal interpretation of the Genesis account of creation. On this definition a theistic evolutionist could also be described as a creationist simply because they believe God created all things.

But the usual assumption of Creationism is also that no macro-evolution is involved, and so all living organisms were created substantially as they now exist, although it is accepted that small changes micro-evolution within created ‘kinds’ Gen 1. On this definition it is not necessary to assume an old earth and Young Earth YE Creationism is the belief that the universe and the Earth are just 6, to 10, years old as inferred from a literal interpretation of the Old Testament.

There are several key organisations working in Creation Science e. The following also provide scientific support for the YE theory: The western media, particularly in Europe, strongly promotes Darwinian evolution and an old earth. The secular scientific community does likewise e. On the other hand, there is also a growing number of professional, peer reviewed well published scientists who favour YE Creationism.

So despite heavy lobbying, the layman like many in the scientific community remains unconvinced. But has the layman studied the subject sufficiently to defend his or her doubt? If the subject of Creation has not been studied, then biblical fundamentals are easily undermined by secular arguments.

Chronological Methods 10 – Obsidian Hydration Dating Obsidian, or volcanic glass, is formed by the rapid cooling of silica-rich lava. Humans often used obsidian as a raw material when making chipped stone tools. In , two geologists, Irving Friedman and Robert Smith, began looking into obsidian’s potential as a time marker. They introduced the obsidian hydration dating method to the archaeological community in

The horse series has long been a showcase of evolution. But in reality, this series is the best argument that can be presented against evolution from the fossil record. 1 Creationists have various opinions on whether the horse series is in fact made up of different created kinds. This article addresses some of the current problems, and concludes that the horse series probably comprise three.

These include reconstructions of continents, calculations of the Apparent Polar Wander Paths APWPs or paleolatitude drift curves, testing the Geocentric Axial Dipole GAD model, studies of geomagnetic paleosecular variation or reversal asymmetries, comparison of coeval results obtained from different types of rocks, estimation of inclination shallowing in sedimentary rocks and understanding the delay in remanence acquisition caused by slow cooling in large intrusions.

Carbon dating Carbon dating is a technique used to determine the approximate age of once-living materials. It is based on the decay rate of the radioactive carbon isotope 14C, a form of carbon taken in by all living organisms while they are alive. Before the twentieth century, determining the age of ancient fossils or artifacts was considered the job of paleontologists or paleontologists, not nuclear physicists.

By comparing the placement of objects with the age of the rock and silt layers in which they were found, scientists could usually make a general estimate of their age.

Is Earth Dating Correct? Before we examine a YE model it is essential to summarize standard dating methods. A discussion of the strengths and weaknesses of conventional radiometric dating (which yields billions of years for the age of the earth) is given at Dating the Earth.A few of the non-conventional dating ‘clocks’ (which invariably point to a young earth) are also discussed.

Electron Spin Resonance, or ESR, dating is a relatively new approach to dating organic material, particularly tooth enamel. It is based on that fact that electrons from cosmic radiation and radioactivity can be trapped in crystalline structures.

Unfortunately, ESR can give dates with large errors. However, if other dating techniques can also be used, then the dates can be substantiated. Recently, paleoanthropologists have begun to use more than one method of dating in order to ensure that the results of dating are fairly accurate.

Geochronology – Nonradiometric dating: In addition to radioactive decay, many other processes have been investigated for their potential usefulness in absolute dating. Unfortunately, they all occur at rates that lack the universal consistency of radioactive decay. Sometimes human observation can be maintained long enough to measure present rates of change, but it is not at all certain on a.

The division is based on differences in mechanical properties and in the method for the transfer of heat. The lithosphere is cooler and more rigid, while the asthenosphere is hotter and flows more easily. In terms of heat transfer, the lithosphere loses heat by conduction , whereas the asthenosphere also transfers heat by convection and has a nearly adiabatic temperature gradient. This division should not be confused with the chemical subdivision of these same layers into the mantle comprising both the asthenosphere and the mantle portion of the lithosphere and the crust: The key principle of plate tectonics is that the lithosphere exists as separate and distinct tectonic plates , which ride on the fluid-like visco-elastic solid asthenosphere.

Tectonic lithosphere plates consist of lithospheric mantle overlain by one or two types of crustal material: Because it is formed at mid-ocean ridges and spreads outwards, its thickness is therefore a function of its distance from the mid-ocean ridge where it was formed. The location where two plates meet is called a plate boundary. Plate boundaries are commonly associated with geological events such as earthquakes and the creation of topographic features such as mountains , volcanoes , mid-ocean ridges , and oceanic trenches.

The majority of the world’s active volcanoes occur along plate boundaries, with the Pacific Plate’s Ring of Fire being the most active and widely known today. These boundaries are discussed in further detail below. Some volcanoes occur in the interiors of plates, and these have been variously attributed to internal plate deformation [7] and to mantle plumes. As explained above, tectonic plates may include continental crust or oceanic crust, and most plates contain both.

Two types of product dating may be shown on a product label. The calendar date provides consumers with information on the estimated period of time for which the product will be of best quality and to help the store determine how long to display the product for sale. Does Federal Law Require Dating? Except for infant formula, product dating is not required by Federal regulations. For meat, poultry, and egg products under the jurisdiction of the Food Safety and Inspection Service FSIS , dates may be voluntarily applied provided they are labeled in a manner that is truthful and not misleading and in compliance with FSIS regulations 1.

To comply, a calendar date must express both the month and day of the month. In the case of shelf-stable and frozen products, the year must also be displayed.

Help a Survivor Sexual Assault According to the Unites States Department of Justice, sexual assault is any type of sexual contact or behavior that occurs without the explicit consent of the recipient. How You Might Feel There is no typical sexual assault or rape survivor, nor is there a typical response to sexual assault. Survivors of rape or sexual assault may experience numbness, confusion, difficulty concentrating, withdrawal, denial, nightmares, flashbacks, rage, anger, revenge, depression, difficulty eating or sleeping, extreme and explainable fear, guilt and self-blame.

Shock Feelings of shock and confusion are common. Problems coping Attempts to end the anxiety and confusion are often made by rationalizing the rape. Survivors might try to forget about the rape and appear outwardly that everything is fine. Crisis Insomnia fear and nightmares may be experienced in this stage. This can mean that feelings about the sexual assault are surfacing.

Realization Anxiety and fear about rape decrease. It may take months or years to heal from the impact of a sexual assault. There are many areas of concern after a sexual assault. With support, a person who has experienced an assault can heal.

Radiometric Dating __________.?

Introduction Many people have been led to believe that carbon dating along with other radioactive dating methods proves the earth to be much older than 6, years old. If the dates received from carbon dating are accurate, it would be a huge problem for those who believe in the Genesis account of creation. However, when one starts with the Bible and interprets the information received from carbon dating accordingly, one will soon learn that in no way does carbon dating disprove the young earth.

Vaalbara was an Archean supercontinent consisting of the Kaapvaal Craton (now located in eastern South Africa) and the Pilbara Craton (now found in north-western Western Australia).E.S. Cheney derived the name from the last four letters of each craton’s name. The two cratons consist of crust dating from to Gya, which would make Vaalbara Earth’s earliest supercontinent.

A special kind of radiocarbon dating: Bomb radiocarbon dating What is an isotope? To understand radiocarbon dating, you first have to understand the word isotope. An isotope is what scientists call two or more forms of the same element. But they still have the same chemical properties. Atoms of the same element that have different numbers of neutrons are called isotopes. Radiocarbon dating uses isotopes of the element carbon. Radiocarbon dating uses carbon isotopes. Radiocarbon dating relies on the carbon isotopes carbon and carbon
