Geoscience Department. Contact Us. About the Staff. The generation of cosmic ray induced isotopes such as 21 Ne and 3 He in rocks exposed at the Earth's surface has recently opened new areas of geologic research, most notably in dating very young or recently exposed rocks not amenable to other dating methods. Surface exposure dating has been applied to research aimed at understanding climate change, development of landforms, constraining erosion rates, and nuclear waste site assessment, and is a rapidly growing and exciting new field in geochronology. The combination of these isotopic dating techniques in a single laboratory will permit visitors, faculty, and students to conduct research on a large variety of problems in geoscience involving materials spanning the entire range of geologic time.

Additional grading characteristics such as the finish, girdle, culet and fluorescence are also detailed on the certificate. A diagram of the diamond displaying any inclusions is also included on the certificate. Ideally a pair will have been cut out of the same rough stone, and by the same cutter. Matching pairs are very rare in nature particularly since both transparent and fancy color diamonds are so rare to find in the first place.
And, the higher the grade of diamond, the harder it will be to find another to match it - finding one perfectly cut, flawless diamond is a rarity, but finding two is an exceedingly rare occurrence these appearing only every few years. The IGL Jewelry certificate is used to document jewelry pieces and identify the characteristics of the precious stones featured in each piece. Each IGL Jewelry certificate features a description of the jewelry piece followed by a statement of the characteristics and grading of the precious stones found in the piece.
In addition, the identification, weight and content of any precious metals found in the piece are described on the certificate. As a further way to identify the jewelry piece, the IGL Jewelry certificate features an enlarged color photograph of the item. If your watch is genuine, an official certificate of authenticity with all the information available in the registers can be delivered.
IGL have equipped ourselves with the most technologically advanced equipment available for the use in the identification and authentication of colored gemstones. IGL Laboratories are equipped with immersion cells, micrometers, spectroscopes, polariscopes, refractometers, specific gravity liquids, binocular microscopes and spectrophotometers. The certificate identifies the variety of the gemstone, its shape, carat weight, cut, color quality, measurements, transparency factor and major optical characteristics.
If the stone has undergone any treatment, this information will be listed on the certificate as well. Upon request, the origin of the gemstone may be determined. Mollusk 2. Shape 3. Size 4.

Lab 8: Relative and Absolute Geological Dating Lab
Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order. Most absolute dates for rocks are obtained with radiometric methods. These use radioactive minerals in rocks as geological clocks. The atoms of some chemical elements have different forms, called isotopes. These break down over time in a process scientists call radioactive decay. Each original isotope, called the parent, gradually decays to form a new isotope, called the daughter. Isotopes are important to geologists because each radioactive element decays at a constant rate, which is unique to that element.

BYU's Geology program is very field-oriented and a global experience. Thanks to the Hamblin Global Fund, geology students have the opportunity to travel the world. Extensive renovation included construction of state-of-the-art classrooms with multimedia capabilities, office space for faculty and graduate assistants, and modern laboratories. The facilities house extensive instrumentation; computer facilities; and mineral, rock, and fossil collections. The location of the university campus on the Wasatch Front near the juncture of the Rocky Mountains, the Colorado Plateau, and the Great Basin provides an incomparable natural laboratory for geology studies. The Department of Geological Sciences utilizes this natural setting, and the many geologic problems that remain in it to be studied, as one of our main assets.
