河南东秦岭分布着四个时代不同的蛇绿岩带,由北向南依次为:1.碾道沟—马市坪蛇绿岩带; 2.汤河—二郎坪—刘山崖—马畈蛇绿岩带;3.洋淇沟—柳树庄—卧虎蛇绿岩带;4.淅川—桐柏—商城蛇绿岩带(图1)。不同岩带的蛇绿岩,尽管规模不等,出露完整程度不一,但均分布在分割不同构造单元的深断裂带附近,且常伴有高压低温变质或混杂堆积带。
There are four different ophiolite belts in East Qinling of Henan Province, from north to south in sequence: 1. Raoogou-Mapingping ophiolite zone; 2. Tanghe-Erlangping-Liushanya-Stirrup Rock belt; 3. Yangqi ditch - willow village - lying tiger ophiolite belt; 4. Xichuan - Tongbai - Mall ophiolite belt (Figure 1). The ophiolites of different rock belts, although of different sizes, have different degrees of completeness of exposure, but they are distributed in the vicinity of deep fault zones with different tectonic units and are often accompanied by high-pressure and low-temperature metamorphism or mixed accumulation zones.
