Description
The age of Earth is estimated to be 4.54 ± 0.05 billion years. This age represents the final stages of Earth's accretion and planetary differentiation. Age estimates are based on evidence from radiometric age-dating of meteoritic material—consistent with the radiometric ages of the oldest-known terrestrial material and lunar samples—and astrophysical accretion models consistent with observations of planet formation in protoplanetary disks. Following the development of radiometric dating in the early 20th century, measurements of lead in uranium-rich minerals showed that some were in excess of a billion years old. The oldest such minerals analyzed to date—small crystals of zircon from the Jack Hills of Western Australia—are at least 4.404 billion years old.

Destiny Range
"Foreman Dexter Sublette cannot understand why a Russian princess has bought the Pinon Ranch. Sonia Stephens, formerly Stephanovich, is indeed a princess. Ignorant of the cattle business, she's about as unlikely a boss as one could imagine. But the wilful aristocrat is tough--the proof is in her surivival of the revolution that destroyed her family. She desperately wants a fresh start on his ranch that she visited as a child. Things are going well for the Pino Ranch until Serge Varoff, Sonia's ex-finance, follows her from Europe and moves in. He hates American equality and can't tolerate Sonia's growing affection for Subette--a mere servant in Varoff''s eyes. Adding to an already explosive situation is neighbor Dom Diego Alviso, Who covets the Pinon's fine horses. He wants them, and he'll do whatever it takes to get them ..."--Page 4 of cover.
Catch and saddle
Clay Hanford knew that when he bought the legal deed to the J P Ranch in Fandango Basin he also bought trouble. The Basin was run by tough, ruthless King Morgan and his two hard-case sons. They claimed the whole basin for their range ... and that meant the J P spread, too. So a legal deed wasn't about to be enough, Clay Hanford knew. It would take powder, bullets and blood to hold onto the J P!
