	General Chemical's Green River operation owes its existence to a huge prehistoric lake that existed about 50 million years ago. At that time, its fresh waters covered roughly 40,000 square miles of what is now southwestern Wyoming. This vast inland sea — called Gosiute Lake by geologists — occupied a portion of the Green River basin. Beginning in the early Eocene geologic period (approximately 35 million years ago) the fresh water lake shrank in size and became saline, expanded and then became fresh water again. As this lake expanded and then contracted, it laid down trona in sedimentary beds up to 37 feet thick and covering nearly 1,000 square miles. In general, the sediments deposited during the saline phase of the lake, which included the trona deposits, are called the Wilkins Peak Member, and the overlying and underlying fresh water deposits are called the Laney Shale Member and Tipton Shale Member, respectively. The resulting deposit is a unique and exceptionally pure combination of sodium carbonates, readily convertible to high quality soda ash. It is estimated to contain 134 billion tons of mineable trona, enough to meet global soda ash demand for hundreds of years at current levels of consumption. click to enlarge	click above or here for brochure General Chemical Industrial Products Inc. 120 Eagle Rock Avenue East Hanover, NJ 07936 Tel: (973) 599-5500 info@genchem.com
