Metallogenic geological characteristics, development and utilization status and metallogenic prospect of rutile ore in Jiangsu Province

Rutile is one of the superior mineral resources in Jiangsu Province, which is the main source of titanium. The titanium ores are concentrated in the ultrahigh pressure metamorphic belt in Northern Jiangsu, that the rutile has better quality and great resource potential. Rutile originated in the eclogite which is composed of garnet, pyroxene, and rutile, the eclogite is also the ore body of rutile which as high comprehensive value. In Jiangsu Province, there are about 2 000 eclogite rocks, but the exploration on them is low, just that eight eclogite rocks are surveyed. Because of the restriction of market, economy and technology, the rocks are usually explored in a certain kind of mineral which has a negative influence on the use of rutile ore. For this reason, summarizes the regional metallogenic geological conditions, the situation of identifies mineral resources, and the current status of development and utilization. And also takes analysis about the degree of resource security, has a conclusion that the rutile in eclogite in Jiangsu Province has favorable metallogenic conditions and good availability use. Uses the method of geological body ore rate to evaluate the rutile in 209 eclogite rocks, as well as the associated garnet and pyroxene. Takes a forecast that there are 30 large deposits of rutile which is abundant in eclogtie rocks and these rocks can guarantee the construction of the national emerging industry. In view of the existing problems, some suggestions are put forward for further exploration, exploitation and utilization.
