抄録

A granophyre cobble was found from conglomerate of the early Carboniferous Altan Ovoo Formation in the Ulaanbaatar Terrane, central Mongolia. The conglomerate occurs in sandstoneshale alternations, is partly matrix-supported and partly clast-supported, and consists largely of rounded pebbles and cobbles of rhyolite with lesser amounts of quartz porphyry, sandstone, mudstone, granite, andesite and granophyre. Clast imbrication, although not common, shows their derivation from the west. The granophyre clast is characterized by having micrographic texture, titanite and secondary pumpellyite. One quartz porphyry clast contains pumpellyite and rock fragments of granophyre very similar to the granophyre clast, suggesting that the granophyre and quartz porphyry are likely to be related in their provenance.
