Application on Remote Sensing Technology in Investigation of Coal Resources in Mangbang Basin of Tengchong County;

Elemental and Pb-Sr-Nd isotopic geochemistry tracing indicates that the high-K volcanic rocks of the Lawuxiang Formation in the Mangkang basin were derived from an EMII enriched mantle in continental subduction caused by transpression.

The author has taken the high-K magmatic rocks in the Nangqian and Mangkang basins at the northern segment of the JRRSZ as examples to date their 40Ar/39Ar ages and determine their genetic mechanism via elemental and isotopic tracing.

Through analyses of tectonic geomorphic features in Tengchong region (24°40′～25°30′N,98°15′～98°45′E), it is considered that the local tensile stress environment existing from the Pliocene is an important factor for the volcano activity.

Valuable seismic recordings acquired and establishment of network for recording microshocks in the area of Tengchong volcano have been summarized in this paper, which include system property of the observation, network layout, and seismic recordings.
