ABSTRACT
Elements of the key species Lenodus variabilis (Sergeeva) have been recovered from samples of the San Juan Formation which is cropping out in Cerro La Chilca section, Central Precordillera (San Juan). These limestones correspond to the last 15 m of this unit and they are composed by packstone- bioclastic wackestone, glauconitic wackestone to bioclastic grainstone. The inding of L. variabilis allows recording the homonymous biozone, been also present in the following biozone (Yangtzeplacognathus crassus Zone), which pointed out similarities between middle Darriwilian conodont biostratigraphic scheme of the Precordillera with those of Baltica and south-central China.

    Lime, or quicklime, is produced from carbonate sedimentary rocks like limestone. Lime is then used for a variety of purposes in building construction, agriculture, medicine, steel manufacture, and paper-making. By the 19th century, manufacture of lime for mortar and plaster was a significant...

    The Ordovician Stanbridge Group of Quebec has long been considered an allochthonous nappe. It is an internally coherent unit that consists of lower slaty limestone overlain by slate, which is correlated with the Highgate and Morses Line formations, respectively, in Vermont. In Quebec, the basal...
