Uranium—lead dating , abbreviated U—Pb dating , is one of the oldest  and most refined of the radiometric dating schemes. It can be used to date rocks that formed and crystallised from about 1 million years to over 4. The method is usually applied to zircon. This mineral incorporates uranium and thorium atoms into its crystal structure , but strongly rejects lead when forming. As a result, newly-formed zircon deposits will contain no lead, meaning that any lead found in the mineral is radiogenic. Since the exact rate at which uranium decays into lead is known, the current ratio of lead to uranium in a sample of the mineral can be used to reliably determine its age. The method relies on two separate decay chains , the uranium series from U to Pb, with a half-life of 4. Uranium decays to lead via a series of alpha and beta decays, in which U with daughter nuclides undergo total eight alpha and six beta decays whereas U with daughters only experience seven alpha and four beta decays.

Waco Police Warning About Online Dating Meetings After 3 Shootings
WACO, Texas — Waco Police have found a connection with the three early morning shootings from last Sunday which killed a year-old man and injured two more men — they were all on the same dating app. Waco PD believes the victims may have been meeting up with someone they met on the app when they were shot, but it is unclear whether they intended to meet with the shooter or not.

The CB chondrites are metal-rich meteorites with characteristics that sharply distinguish them from other chondrite groups. Their unusual chemical and petrologic features and a young formation age of bulk chondrules dated from the CB a chondrite Gujba are interpreted to reflect a single-stage impact origin. Here, we report high-precision internal isochrons for four individual chondrules of the Gujba chondrite to probe the formation history of CB chondrites and evaluate the concordancy of relevant short-lived radionuclide chronometers.
All four chondrules define a brief formation interval with a weighted mean age of Formation in a debris disk mostly devoid of nebular gas and dust sets an upper limit for the solar protoplanetary disk lifetime at 4. Finally, given the well-behaved Pb-Pb systematics of all four chondrules, a precise formation age and the concordancy of the Mn-Cr, Hf-W, and I-Xe short-lived radionuclide relative chronometers, we propose that Gujba may serve as a suitable time anchor for these systems.
They have been extensively studied Grossman et al. Recent isotope data Connelly et al. Chondrules reflect some of the most energetic processes that operated in the early solar system. The source of the thermal energy is still vigorously debated with different models including shock waves Boss and Graham ; Connolly and Love ; Hood , current sheets Joung et al.
Nebular shock waves currently represents the most widely accepted model Desch et al. All these models take place in the presence of gas in the solar nebula. The discovery of the CB-CH chondrites and their unique properties brought the first serious arguments in favor of chondrule formation in a planetary setting Krot et al. More recently, Johnson et al.
