1984年《中国地质》第七期在《豫南金伯利岩体群若干特征》一文中,除了报道众所周知的金伯利角砾岩、金伯利凝灰岩及斑状金伯利岩外,还首次报道了在豫南发现了金伯利集块岩。由于这种岩石类型十分罕见,笔者在此作一简要介绍: 豫南金伯利集块岩的主要特征:岩石呈灰绿至杂灰绿色。集块在岩石中分布杂乱。集块大小不等,一般多在10至20厘米之间,并常混有角砾或岩屑等。其中熔蚀蚀变的斜方辉橄岩块可达18×24(厘米);熔蚀蚀变的辉石岩岩块可达50×60(厘米);榴辉岩块可达40×60(厘米)、一些大理岩或斜长角闪片岩岩块直径可达1米以上。集块大小混杂。集块的岩石成分极为复杂,野外查明的岩石类型就达七十种之多。其中有熔蚀蚀变的纯橄榄岩、斜方辉石橄
In addition to the reports of the well-known kimberlite conglomerate, kimberlite tuff, and porphyritic kimberlite, the seventh issue of “China Geology” in 1984, entitled “Several Features of the Kimberlite Group in South Henan,” was also reported for the first time in Kimberley Set rock. Due to the very rare type of rock, I briefly introduce here: The main feature of the kimberlite-massif in southern Henan: the rocks are gray-green to gray-green. Set pieces in the rock distribution messy. Set pieces ranging in size, generally more than 10 to 20 cm, and often mixed with breccia or debris and so on. Among them, the eclogite horizons up to 18 × 24 (centimeter), the corroded alteration pyroxenite blocks up to 50 × 60 (cm), the eclogite blocks up to 40 × 60 Cm), some marble or plagioclase flash rock block diameter of up to 1 meter above. Block size mixed. The rock composition of the blocks is extremely complex, with as many as 70 rock types identified in the wild. Among them, there are eroded and altered dunite and orthopyroxene
