Calcium carbonate content has been determined ashore for each sample using a Ber-nard calcimeter. For each sample the sand fraction (63-2000 µm) was sieved, dried, and weighed. No H2O2 was used, to avoid an artificial fragmentation of the planktonic foraminifers. The composition of the total sand fraction was studied under the microscope, and
أكمل القراءةSand Dunes are also found along I-70 in Dickinson and Saline counties. Loose sand is found in parts of the Ogallala Formation (Tertiary) along old river deposits in western Kansas. Sandstones consist largely of quartz grains and are held together by some natural cement or matrix such as calcium carbonate, iron oxide, silica cement, or clay.
