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:Abstract(#br)The Han-Xing iron mineralization in the central North China Craton is a typical Fe skarn deposit associated with altered diorites. Here we report the Fe isotopic compositions of whole rocks and mineral separates from this deposit with a view to evaluate the Fe iso...

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:... Most of the known skarn-type Fe deposits are located in areas with high reconstruction errors or anomaly scores in the anomaly map, indicating that these anomalies may be related to Fe mineralization.

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...
