Abstract
Secondary dolomitization of reef formations is a fairly common phenomenon. Regardless of reef formation in the arid or humid climate, both isolated reefs and reefs of asymmetric reef systems are affected by this process. The article discusses the sources of Mg and methods of its input into reefs, as well as conditions of these processes and the removal of soluble reaction products. This element can be sourced both from relatively deep-water depression-filling sediments (synchronous to the reef) and from clay or salt rocks in the reef topography infill. The possibility of free filtration and removal of the dissolved reaction products is mandatory for this process. If the latter condition is absent, reefs retain their primary calcareous composition.
期刊介绍:
Lithology and Mineral Resources is an international peer reviewed journal that publishes articles on a wide range of problems related to the formation of sedimentary rocks and ores. Special attention is given to comparison of ancient sedimentary rock and ore formation with present-day processes. The major part of the journal is devoted to comparative analysis of sedimentary processes on the continents and in oceans, as well as the genetic aspects of the formation of sedimentary and hydrothermal–sedimentary mineral resources. The journal welcomes manuscripts from all countries in the English or Russian language.
