土壤氡测量技术在新疆塔什库尔干县地热资源勘查中的应用
The application of soil radon measurement technology to geothermal exploration in Taxkorgan county, Xinjiang
摘要
Abstract
Soil radon measurement technology is an effective means for geothermal exploration, and its purpose is to determine the bur-ied faults and the geothermal fluid accumulation area. 1 904 groups of data were collected through measuring soil radon in the study area and by means of point-network control and profile-linear tracing. According to the sources of different loose layers, the authors ana-lyzed the data using the partition and piecewise methods, and discovered significant difference in soil radon in different layers. The soil radon background value is 392.1 Bq/m3 in the metamorphic clastic accumulation, 1 930.2 Bq/m3 in the granite debris, and 1 571.1 Bq/m3 in the syenite and granite melange. The dispersion degree of the data was calculated and the anomaly threshold was determined. And on such a basis, the characteristics of soil radon distribution were analyzed. It is shown that the high value anomaly of soil radon can better indicate the locations of buried faults and geothermal anomalous zones.关键词
