Abstract

The Mérida wollastonite mineralizations are located in the inner part of a contactmetamorphic aureole developed on impure limestone by a late Hercynian granite. The masses are largely monomineralic, and consist of fibrous and bladed crystals of wollastonite-Tc, which are generally clase to pure CaSi03 in chemical composition, indicating the lack of metasomatic additions of Fe and Mn. According to available data, the wollastonite was formed from chert layers embedded in limestone, by local exchange between CaO and Si02, resulting in a reaction skarn.
