The sharp difference suggests that they have different origins: the former comes from allochthonous sapropel-type organisms of the lower strata and is the remains of crude oil, and the latter is autochthonous humic-type organic matter of sedimentary rocks between the basalt layers.

玄武岩中铜矿石沥青的δ13CV-PDB为-27.3‰～-33.2‰，平均-31.97‰，沉积岩中铜矿石碳质的δ13Cv-PDB为-20.2‰～-23.2‰，平均-22.11‰，表明二者无明显成因联系，前者属腐泥型，为石油的遗迹，来自下部地层；后者为腐植型，来自原地沉积的陆生高等植物。

An interbedded sliding zone with fault-slip cleavage in an amygdaloidal basalt thin layer made up the embryo of the main sliding zone and the coupling chemical weathering with physical weathering based on lateral unloading made the interbedded sliding zone get a material prone to slide finally.

褶皱运动产生的构造裂隙与柱状节理的叠加使滑体玄武岩呈现碎裂—镶嵌结构，而沿结构面发生的化学风化形成的腐岩壳使岩体进一步转变为&石夹土&结构，加剧了坡体的时效变形。

The study of their precise UPb geochronology and characteristics of rock associations shows that (1) small amount of EarlyTriassic (~248 Ma) volcanic rocks were preserved and cropped out in the area, which consist mainly of thin bed of andesitic rocks intercalated with minor basaltic andesites; that (2) the MiddleTriassic magmatism was characterized by extensive felsic igneous rocks with minor basalts interbedded in the middle of volcanic sections in part of areas, and the late MiddleTriassic rhyolites and main body of Lincang granitic batholith have the same extrusive/intrusive time with the age of ~230 Ma; that (3) the LateTriassic volcanic sequences are principally composed of basalts with minor interlayered rhyolites, exhibiting typical characteristics of bimodal volcanics.

三叠纪岩浆作用广泛发育于澜沧江南带，锆石UPb年代学结果及岩石组合特征显示：(1)该区残留有少量的早三叠世火山岩(约248 Ma)，主要为一套薄层的以安山岩为主的火山岩；(2)中三叠世以大规模的酸性岩浆作用为主，部分地段的中部夹有少量的玄武岩，其中晚期的流纹岩与该区出露巨大的临沧花岗岩基主体具有一致的形成时代(约230 Ma)；(3)晚三叠世则以基性火山岩为主，夹少量流纹岩为特征的&双峰式&火山岩组合。

In addition, the features of elemental geochemistry of all samples suggest that (1) the EarlyTriassic andesitic rocks, characterized by characteristic natures of island arc volcanics, likely erupted in the subduction setting; that (2) the generation of LateTriassic rhyolites with an affinity of Alike granite and synchronously main body granites in the Lincang batholith displaying similar geochemical features, is closely related with the postcollision or latecollision setting; that (3) although the LateTriassic basic rocks partly show island arc volcanics such as highAl contents and NbTa depletion, some of them possessing highMg contents and mostly having traceelement ratios similar to intraplate basalt, which indicates that they erupted in the postcollision rift environment.

元素地球化学特征表明，早三叠世火山岩具有典型的岛弧火山岩的特征，暗示其很可能形成于俯冲的构造环境；中三叠世晚期的流纹岩与临沧花岗岩基主体具有非常相似的地球化学特征，结合其流纹岩具有A型花岗岩属性，表明该区中三叠世火成岩形成于碰撞后的构造背景；而晚三叠世基性火山岩虽然在地球化学特征上显示出与岛弧火山岩相似的高铝和NbTa的亏损，但其中部分火山岩具有高镁和板内玄武岩的微量元素比值特征，说明这些火山岩可能形成于碰撞后裂谷环境。

3 Ma: from the basalt beds under the Jingangshan bed of the Yixian Formation, and 120.3 Ma: from the lower part of the Jiufotang Formation,showing an age of late Early Aptian.

122.3Ma：义县组金刚山层之下的玄武岩，120.3Ma：九佛堂组下部，表明其时代为早阿普丁阶晚期。

Tests of one readily available Mars soil simulant, a ground-up basaltic rock called 'baghouse dust', did not go as hoped.

在火星土壤模拟试验过程中，一种被称作&沉渣室尘埃&的玄武岩并没产生预期效果。

The petrophysical properties of volcanic rock reservoirs in Junggar Basin are generally characterized by the following: the acidic lava and auto brecciated lava are the best, especially the petrophysical properties of auto brecciated lava and andesites after the tectonic movement and denudation process in the later stages are superior to those of basalts.

准噶尔盆地火山岩储层物性一般特点是：酸性熔岩、火山角砾岩最好，特别是经后期构造运动和溶蚀作用改造后的火山角砾岩；安山岩的物性总体优于玄武岩。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
