Leaota , mesovoid shallow substratum (MSS), mineralogical composition, scree, schist.
This paper presents the results of the mineralogical and chemical analysis made on crystalline schist that covers most of Leaota Mountains. The relief developed on schist substratum must be specific to those mountains, covering, by far, approximately three quarters of their surface. Our studies on the mineralogical composition of crystalline schist are part of a research complex whose main objective is the mesovoid shallow substratum (MSS) or shallow subterranean habitats (SSHs) hosted by the scree that covers some slopes of Leaota Mountains. In fact, the scree, through interclastic porosity, through the micro-climate particularities, represents a very interesting and individualized living environment which has an essential ecologic role (Nitzu et al, 2010; Nitzu et al, 2014, Mammola et al, 2017). The microfauna elements, temporarily or permanently hosted by the scree were correlated to the geological substratum type, analyzing the way through which the different geological substratum type leads, in turn, to differences amongst the distribution of the fauna elements. The mechanical, chemical, biochemical behavior of the crystalline schists on the weathering is reflected by its ability to favor, more or less, the installation of microfauna.
