With the increasing of the rock detritus content, the uniaxial compressive strength and Young's modulus increase; the elastic strain energy index and bursting energy index of studied the rocks increase; the duration of failure decrease.
随着碎屑颗粒粒径的增大,即由砂质泥岩、粉砂岩向砂岩过渡,粗粒的粒柱状矿物逐渐增加,而细粒的片状矿物逐渐减少,岩石的强度和刚性增强,在集中应力作用下,弹性能指数增大,发生脆性破坏的可能性增大及破坏持续的时间变短也更猛烈,岩石的冲击倾向性增强。

By TM images the linear structures, water system, the outer edge of Tianchi Volcano trachite are extracted. By the sensitivity of SAR images to geomorphology, the distribution of parasitical volcano cone and lava fornix around Tianchi volcano are interpreted. With the aerial photos the parasitical lava of Qixiangzhan, Baiyun and Bingchang stage are filtered. At the same time by orthogonal cross-course wavelet transform, texture analysis is carried on to ERS-2 SAR images, and the texture characters are filtered. On the basis of the spectrum character of multi-band of TM images, multi-band algebraic grouping is made, and the factor of texture character factor and band grouping of TM images are input to BP neural network classification model. The good classified results are received.
利用TM图像对线性构造、水系、天池火山粗面岩锥体外边缘的提取;利用SAR图像对地形敏感特性,提取了天池火山周围寄生火山锥体及熔岩穹丘的分布;利用航片对天池火山口周围的气象站期、白云期、冰场期等寄生喷发物进行了提取:同时利用正交小波变换对ERS-2 SAR图像进行了纹理分析,提取了纹理特征:根据TM图像不同波段的光谱特征,进行了波段代数组合,并把纹理特征参数与TM图像的波段组合及DEM一起输入BP神经元网络分类器,取得了较好的分类效果。

Rare elements and REE are mainly enriched in gray-black trachyte and less in other rocks. In addition, schistosity, pyritization, silicification and carbonation in gray-black trachyte are contributed to enrich rare element and REE. It is suggested that alkaline rocks in Hongyang area have the characteristics of subvocanics, and alkaline rocks in Hongyang and Miaoya areas all came from upper mantle and mixed with some substances of crust. Intrusion of alkaline rocks is related to the occurrence, development and evolvement of the deep rupture zone in the areas.
稀土、稀有元素主要富集于灰黑色粗面岩中,而在其他岩石类型中相对较少,同时岩石的片理化、黄铁矿化、硅化和碳酸盐化对稀土、稀有元素有进一步的富集作用;提出了本区的碱性岩组合具有次火山岩相的特征,讨论了本区碱性岩的成因,认为其与湖北庙垭地区的碱性岩可能均来自上地幔,并不同程度地混染了大陆壳的物质成分,其形成时代与断裂构造带的发生、发展和演化基本同步。
