| Abstract: | Indosinian hypabyssal rocks in East Kulun mountains' middle belt consist of diritic porphyrite, andesitic porphyrite, porphyrite and cryptoexplos ive breccia. According to the study on the petrology and geochemical characteris tics, the rocks belong to HK-cale alkaline volcanic suite. In the north pal eo-Tethys, they were formed under the active continental margin or volcanic arc environment. During the Indosinian period, the subduction of oceanic crust and closure of Paleo-Tethys cause extensive volcanism and magmatism. |
