火山地层具有特殊的时空属性和地质记录特征,但在盆地充填分析时未引起足够重视.为进一步明确火山地层的地质属性,利用松辽盆地下白垩统营城组全取心浅钻井(营一D1和营三D1井)资料开展火山地层构成要素特征及地质意义研究.营一D1井营城组一段和营三D1井营城组三段火山地层分别识别出3个和2个喷发间断不整合界面、10个和8个喷发整合/不整合界面.根据喷发间断不整合界面属性可知,营一D1井和营三D1井火山地层可分别划分为4个和3个火山机构,稀土和微量元素对火山机构有较好的响应.堆积单元有简单熔岩流、辫状熔岩流、穹丘、热碎屑流、热基浪和火山泥石流6类,熔岩类单元喷发时的火山气体排放强度弱于火山碎屑岩类单元.火山地层具有建造时间短暂和间断时间长久的时间属性,火山地层的建造速率不能简单地利用地层厚度和测试的顶底时间差来计算.

Land surface temperature(LST) directly affects the energy balance of terrestrial surface systems and impacts regional resources, ecosystem evolution, and ecosystem structures. Xinjiang Uygur Autonomous Region is located at the arid Northwest China and is extremely sensitive to climate change. There is an urgent need to understand the distribution patterns of LST in this area and quantitatively measure the nature and intensity of the impacts of the major driving factors from a spatial perspective, as well as elucidate the formation mechanisms. In this study, we used the MOD11C3 LST product developed on the basis of Moderate Resolution Imaging Spectroradiometer(MODIS) to conduct regression analysis and determine the spatiotemporal variation and differentiation pattern of LST in Xinjiang from 2000 to 2020. We analyzed the driving mechanisms of spatial heterogeneity of LST in Xinjiang and the six geomorphic zones(the Altay Mountains, Junggar Basin, Tianshan Mountains, Tarim Basin, Turpan-Hami(Tuha) Basin, and Pakakuna Mountain Group) using geographical detector(Geodetector) and geographically weighted regression(GWR) models. The warming rate of LST in Xinjiang during the study period was 0.24℃/10a, and the spatial distribution pattern of LST had obvious topographic imprints, with 87.20% of the warming zone located in the Gobi desert and areas with frequent human activities, and the cooling zone mainly located in the mountainous areas. The seasonal LST in Xinjiang was at a cooling rate of 0.09℃/10a in autumn, and showed a warming trend in other seasons. Digital elevation model(DEM), latitude, wind speed, precipitation, normalized difference vegetation index(NDVI), and sunshine duration in the single-factor and interactive detections were the key factors driving the LST changes. The direction and intensity of each major driving factor on the spatial variations of LST in the study area were heterogeneous. The negative feedback effect of DEM on the spatial differentiation o
