| 中文摘要: |
| 在黔湘桂一带，湖南黔阳-溆浦-城步的白马山-中华山-崇阳坪-瓦屋塘、五团-苗儿山-越城岭及广西融安-贵州从江的摩天岭、元宝山，地表出露花岗岩体上反映为重力低、磁力低的地球物理场响应特征。在贵州梵净山、九万大山出露花岗岩体也表现为重力低、磁力低及高电阻率的物理性质，与邻省的极其相似。因此，本文根据中酸性岩浆岩的物性表征，以剩余重力值-2×10-5m／s2、磁场强度值-10nT等量线为基础，外加布格重力异常负圈闭，圈定了贵州境内逾百处隐伏岩体分布，其推测的成果对寻找与中酸性岩体有关矿产具有指示作用。 |
| 英文摘要: |
| Around many areas of southeast China, such as the Baimashan-Zhonghuashan-Chongyangpin-Wawutang of Qianyang-Xupu-Chengbu and Wutuan-Miao’ershan-Yuechengling in Hunan Province, Rongan of Guangxi, and Motianling and Yuanbaoshan in Chongjiang of Guizhou Province, low gravity and low magnetic anomalies characterize the exposed granite bodies on the surface. Similar features also appear in Fanjingshan and Jiuwandashan of Guizhou Province. In such a setting, according to characterization of physical properties of intermediate-acidic magmatic rock, using contours of residual gravity anomalies of -2×10-5m／s2 and magnetic field intensity of -10nT, plus negative Bouguer gravity anomalies, this paper delineates over a hundred sites with distribution of concealed pluton. The results may provide indicators for prospecting minerals in connection with intermediate-acidic pluton in Guizhou. |
