Dolomite Cave Deposits from Carlsbad Caverns

John Thrailkill


A number of speleothems (cave deposits) from Carlsbad Caverns, New Mexico have been found to contain secondary dolomite. One such speleothem, studied by microscopic, X-ray, and staining techniques, consisted of a mixture of protodolomite and high-magnesium calcite. The dolomite is apparently pseudomorphic after and derived from aragonite at temperatures less than 20°C. and in contact with water in which aMg++/aCa++ was high and dolomite probably stable relative to calcite.
