Geothermal resources are crucial for sustainable energy development, yet accurately detecting geothermal anomalies in complex terrains remains a significant challenge. This study develops multi-source thermal infrared approach to enhance anomaly detection using Landsat 8 and ASTER land surface temperature (LST) data. The Yangbajing–Yangyi Basin Tibet, characterized by high altitude rugged topography, serves as the area. winter time-series data from 2013 2023 were processed on Google Earth...
The post-collisional Gangdese metallogenic belt with over 45 Mt Cu has attracted worldwide attention. We report the whole-rock geochemistry, zircon SIMS U–Pb geochronology, and in situ Hf–O isotopic compositions of Jiama deposit belt. intermediate to felsic intrusive rocks are characterized by high SiO2 (64.8 78.8 wt. %) Al2O3 (12.1 16.3 contents, Sr/Y ratios (43–74), showing geochemical characteristics adakites. Zircons from four intrusives yield ages 16.19 ± 0.20 Ma, 15.67 0.32 15.44 0.16...
本文采用短波-热红外光谱联合测量技术+矿物地球化学分析手段,以川西打枪沟花岗伟晶岩型Li-Be稀有金属矿床的13个钻孔岩心样品为研究对象,开展了花岗伟晶岩型稀有金属矿床蚀变系统与矿物光谱-地球化学特征的耦合性研究。结果表明:(1)研究区蚀变分带特征表现为(浅→深):白云母→白云母+钠长石→白云母+角闪石+黑云母+其他斜长石,其中Li、Be矿体均赋存于白云母+钠长石蚀变带。(2)白云母矿物地球化学计算结果显示研究区短波白云母(波长小于2200nm),形成压力在0.03~0.25GPa之间,形成深度为1.3~9.6km,相关矿化类型为Li-Be;波长位于2200~2206nm之间的白云母,形成压力在0.16~0.38GPa之间,深度为6.1~14.5km,相关矿化类型为Be;长波白云母(波长大于2206nm)形成压力为0.45GPa,形成深度为17.1km,无矿化。由此认为研究区成矿环境温度在200~500℃之间、压力在0.03~0.34GPa之间、成矿深度在1.3~14.5km之间。(3)与Li矿化相关的白云母波长均小于2200nm,位移处于10nm波动范围,说明Li矿可能形成于岩...
Field measurements of the thermal infrared (TIR) reflectance from drill hole samples proved to be an effective method map variations in garnet species associated with hydrothermal alteration zonation Jiama porphyry-skarn Cu deposit 1# skarn orebody, Tibetan Plateau, China. The TIR mineral spectral information was combined electron probe micro-analysis (EPMA) provide geological insights on effectively determining (a) end components and providing a format for further research type genesis...
Abstract The Tieshanlong ore field is an important part of the Nanling Range, which famous worldwide for its W‐Sn mineralization. Notably, mineralization age not well constrained, and our investigation reveals that granitic emplacement occurred at different stages. However, previous studies have distinguished these multiple stages magmatism. granite complex closely related to Huangsha quartz vein‐type deposit Tongling skarn‐type Cu‐W‐Sn in this field. Through investigations isotopic...
朱溪是近年来在江西塔前-赋春成矿带发现的一个世界级超大型钨铜矿床。本文采用短波红外+热红外光谱技术对矿区13个钻孔进行了光谱测量，结合岩石-矿物地球化学分析，探讨了朱溪矿床矽卡岩中典型蚀变矿物的形成与演化过程，厘定了矽卡岩形成不同阶段矿物组合的光谱特征，构建了朱溪矿床的短波红外+热红外光谱勘查模型。研究发现:（1）区内不同矿物组合形成了明显的蚀变分带，由内向外依次为绢云母（富Si）+长石（岩体顶层蚀变，多期流体叠加综合作用）→外矽卡岩:钙铝榴石+透辉石+（绢云母）→透辉石+蛇纹石+绿泥（帘）石+滑石→绢云母（富Al）+绿泥（帘）石（基底不整合面蚀变）；（2）Al-OH波长的移动可指示成矿流体压力、温度及pH值的变化；（3）研究区透辉石的形成、演化与矿体之间关系密切，虽然富矿体赋存于矽卡岩形成早期的透辉石-石榴子石蚀变带，但大量矿体则赋存于矽卡岩退蚀变阶段的蛇纹石-绿泥石蚀变带；（4）矿体的形成与流体的混合作用关系极大，伊利石光谱吸收特征能够指示外部冷水（大气降水或地下水）的灌入轨迹。;The Zhuxi tungsten polymetallic giant deposit...
The identification of primary geochemical haloes can be used to predict mineral resources in deep-seated orebodies through the delineation element distributions. Jiama deposits a typical skarn–porphyry Cu–polymetallic deposit Gangdese metallogenic belt Tibet. skarn, Cu–Mo hornfels, and Mo ± Cu porphyry mineralization there exhibit superimposed at depth. Three-dimensional (3D) halo modeling was undertaken for with aim providing data describe distributions 3D space. An overall zonation Zn(Pb)...
As an important part of spatial data, remote sensing data also has the characteristic uncertainty existing in acquisition, pre-processing, information extraction, classification and evaluation. To these characteristics, concepts mineralized alterations repeatability was put forward. Using Duolong porphyry copper deposit, Tibet as example, discussed. Results show that same sensor were similar under circumstance time phase which does not vary much, but results will be partially different when...
