Abstract
The activity of the first Hercynian tectonic phase is documented in the Lake Mulargia area (central Sardinia) by the presence of numerous tectonic units. We have examined in particular the southern region of the lake, where one of the upper tectonic units (the Bruncu Maresusus Unit) outcrops. It has at its base a thick silicoclastic succession where we have found Tremadocian Acritarchs in its stratigraphically upper part. This formation is time—equivalent to the Solanas Formation and the Arenarie di San Vito Auct. Another tectonic unit, Bruncu Brevexilis, constitu ted from bottom to top of metavolcanities of probable middle Ordovician age and fossiliferous sediments of Caradocian, Silurian and Devonian age, is also present in the same area and lies under the Bruncu Maresusus Unit.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
