Dolomite sedimentary rock.
Metasedimentary and igneous rocks outcrop over the central portion of the map area (designated as IM on Fig. 40.2 ). Seabed relief on bedrock reaches 40 m in places (over a horizontal distance of ~500 m) but is generally less than 6 m ( Fig. 40.3 ). At regional scale the igneous bedrock exhibits two jointing directions (approximately 40° and ...
Dolomite often forms when limestone recrystallizes after burial. Many limestones are biochemical; some may be chemical (inorganically precipitated). Evaporite rocks form when sea water or lake water dries up and precipitates gypsum (CaSO 4 ·2H 2 O), halite (NaCl), or other minerals. Evaporites are chemical sedimentary rocks.Synonyms to luxury and modernism, dolomite, also known as dolostone, is a sedimentary rock composed of the mineral dolomite.
