Abstract Cretaceous igneous rocks in SW Borneo are significant for investigating the Paleo-Pacific subduction and regional correlation. This paper presents new zircon ages Sr–Nd–Pb–Hf–O isotopic whole-rock geochemical data granitoids Schwaner Mountains. These granitoid samples yield formation of 92–80 Ma can be geochemically subdivided into Group 1 biotite granite granodiorite 2 monzogranite. has higher εHf t values +1.2–+14.5 lower δ18O 5.2–6.6‰ than with −1.5–+5.9 6.1–6.6‰, respectively....
Mesozoic granitoids in Peninsular Malaysia provide crucial information on the temporal–spatial relationship between Tethyan and Palaeo-Pacific domains. This paper presents new ages geochemical data for newly identified Jurassic–Cretaceous granites meta-granites from East Malaya. These can be divided into three groups. Group 1 consists of high-K calc-alkaline granodiorites (171–162 Ma) with variable ε Nd ( t ) values −7.4–+0.5, zircon Hf −7.4–+8.6, high initial ratios 206 Pb/ 204 Pb...
The health hazards caused by low concentrations of Pb2+ ions in drinking water systems are significant concern. In order to remove and retain Na+, K+, Ca2+ Mg2+ as harmless competitive without simultaneous removal, nickel foam (NF)/Mn2CoO4@tannic acid (TA)-Fe3+ electrodes were prepared a hydrothermal method coating an asymmetric capacitive deionization (CDI) system is established using the graphite paper positive electrode. designed CDI exhibited high adsorption capacity 375 mg g-1 with...
Abstract The geodynamic evolution of the Palaeo-Tethyan Ocean is key to understanding development Pangaea. main continents SE Asia were welded together in response closure Ocean. However, precise location sutures and timing collisions are poorly constrained, especially southward continuation from Peninsular Malaysia into west Indonesia. This study presents new zircon U–Pb geochronological, petrological, elemental Sr–Nd–Pb–Hf–O isotopic data order investigate origin tectonic setting...
摘要: 昆嵩地体位于印支陆块的核部，记录了大量的印支期岩浆作用和构造热事件，是了解古特提斯洋演化及印支与华南陆块碰撞拼合过程的关键区域，但目前对该期岩浆事件的成因及其与北部长山带的关系未能得到有效厘定.对昆嵩地体绥安（Huyện Tuy An）和胶寮（Chu Loan）地区的Van Canh花岗岩开展了岩相学、锆石U-Pb年代学、锆石原位Hf同位素和全岩地球化学分析，以限定其形成时代、岩石成因及构造环境.锆石U-Pb定年显示花岗岩样品的结晶年龄为244~239 Ma.该套样品包括了二长花岗岩和钾长花岗岩，均属于高钾钙碱性系列.它们的A/CNK值为1.03~1.21，为S型花岗岩.花岗岩均显示明显的Rb、Th和U富集，以及Nb、Sr、Zr和Ti的亏损，并具有强烈的Eu负异常（Eu/Eu*=0.24~0.56）.锆石具有富集的原位Hf同位素组成（εHf（t）=-11.2~-0.7）以及古-中元古代的Hf二阶模式年龄（TDM2=1.98~1.31...
