Document Summary

Hcl + caco3 -> cacl + co2 (g: compaction: the primary physical process of lithification where grains of sediment are squeezed together beneath the weight of overlying sediment. xi. Cementation: a process where minerals precipitate from watery solutions that percolate through the pores between grains of sediment: cement gives sedimentary rocks their color, red bed: red siliciclastic sedimentary rocks. xii. Flint: composed of extremely small quartz crystals that have precipitated from watery solutions (chert, or precipitated sio2). xiii. Banded iron formations: complex rocks that consist of oxides, sulfides or carbonates of iron interlayered with thin beds of chert. xiv. Oolites: sediments or rocks consisted of nearly spherical grains that can be seen to grow in modern seas by rolling about and accumulating aragonite needles. xv. Intraclasts: fragments of preexisting seafloor material that gets ripped up during storms or other sudden eluents. xvi.
