MOR型蛇绿岩中地幔橄榄岩的地质特征
Geological features of MOR-type ophiolitic peridotites
摘要
Abstract
Mantle peridotites, originated from sub-continental, sub-arc or sub-ridge mantle lithosphere, commonly occur in orogenic belts as Alpine-type peridotites or members of ophiolites through tectonic emplacement, or exist in the volcanic rocks as xenoliths. In this paper, we compared the petrological, geochemical, isotopic characteristics of the mantle peridotites from four MOR-type ophiolite candidates with those of abyssal peridotites. As a consequence, we believe that a comparison in geological characteristics with abyssal peridotites could be an effective way in distinguishing MOR-type peridotites as well as restoring the tectonic settings of MOR-type ophiolites.关键词
