The complex geology of Oklahoma is the reason for its abundant mineral resources including petroleum (oil and natural gas), coal, metals (examples include copper, lead, zinc), and industrial minerals (examples are limestone, gypsum, iodine, sand and gravel). Can you find diamonds in quartz? Diamonds have a specific gravity of 3.1–3.5.Salinity impedes soil and crop productivity in over 900 million ha of arable lands worldwide due to the excessive accumulation of salt (NaCl). To utilize saline soils in agriculture, halophytes (salt-tolerant plants) are commonly cultivated. However, most food crops are glycophytes (salt-sensitive). Thus, to enhance the productivity of saline soils, …

The keys to identifying chalk are its hardness, its fossil content, and its acid reaction. At a glance, diatomite and gypsum rock have a similar appearance. An examination with a hand lens will often reveal the fossil content, separating it from gypsum. Its reaction with dilute (5%) hydrochloric acid will separate it from both gypsum and diatomite. Formed by chemical precipitation from a concentrated solution in water as salt, gypsum, or limestone.
