Cherty limestone

Oolitic limestone is most likely to form in what type of depositional environment? Shallow, clear, marine waters with vigorous current activity ___ sandstone contains abundant feldspar, suggesting that the sand was derived by weathering and erosion of granitic bedrock. .

Geology: The Boone Formation consists of gray, fine- to coarse-grained fossiliferous limestone interbedded with chert. Some sections may be predominantly limestone or chert. The cherts are dark in color in the lower part of the sequence and light in the upper part. The quantity of chert varies considerably both vertically and horizontally.Limestone mining and utilization in Missouri began in the mid 1800s. The amount mined prior to 1920 is not known for certain. Since that time, however, reliable statistics do indicate that 3.1 billion short tons of limestone having a present value of about $17.5 billion have been mined in Missouri from 1920 to present.Cherty limestone (1st option) 640 Cherty limestone (2nd option) 641 Dolomitic limestone, limy dolostone, or limy dolomite 642 Dolostone or dolomite 643 Crossbedded dolostone or dolomite 644 Oolitic dolostone or dolomite.
