摘要:Abstract(#br)The Jinling complex is spatially and temporally associated with the Jinling skarn-type iron deposit. The complex is composed of biotite diorite, hornblende diorite, monzonite and quartz diorite. U–Pb dating of zircons from the biotite diorite and monzonite using l...

摘要:Abstract(#br)The Zhangmatun deposit is a high-grade skarn-type iron deposit genetically linked with a gabbroic intrusion, and it has been recognized as a typical example of “Cornwall-type” deposits in China. Electron microprobe (EMPA) and laser ablation-inductively couple...

摘要:... It is spatially and temporally associated with the Zhangmatun skarn-type high-grade iron deposit. U–Pb dating of zircons from the Zhangmatun gabbro yielded an age of 130.2 ± 1.8 Ma, indicating the emplacement time as Early Cretaceous. The Zhangmatun gabbro displays porph...

摘要:Abstract(#br)The Makeng Fe(− Mo) deposit is the largest Fe deposit in the southwestern Fujian depression belt in southern China. Although it has been extensively studied, there are different views on the genesis of the deposit. In the present study, Sr–Nd–Pb isotope data...

摘要:... The cost of false negative errors differs from the cost of false positive errors because false positive errors lead to wasting much more financial and material resources, whereas false negative errors result in the loss of mineral deposits. Traditional machine learning algo...

摘要:... The prediction rate and the area under the curve (AUC) values show that areas with higher probability have a strong spatial relationship with the known mineral deposits. Comparing the results with original logistic regression (OLR) demonstrates that the GIS-based RELR perform...

摘要:... The integrated map of local Moran's I for these five elements, produced by principal components analysis, was decomposed into two components using the spectrum–area fractal model: a background map and an anomaly map, and the latter showed that the areas linked to high values have a strong spatial correlation with the known skarn-type...

摘要:... Four geological features were considered important for mineral prospectivity mapping based on the geological model for skarn deposits in the belt: (1) the Yanshanian granitic intrusions, because they provided energy, fluids, and part of the metal budget; (2) faults, becaus...

摘要:Abstract(#br) The Janggun iron deposits, Republic of␣Korea, occur as lens-shaped magnesian skarn, magnetite and base-metal sulfide orebodies developed in the Cambrian Janggun Limestone Formation. Mineralization stage of the deposits can be divided into two separate events. The...
