In this paper, we focused on the characteristics of seismo-ionospheric effects related to two successive earthquakes, namely, earthquakes in 2022 Taitung Sea, Taiwan, China, with magnitudes (M) 6.7 and 6.3, at 23.45° N, 121.55° E 23.39° 121.52° same focal depth 20 km, which were detected by China Seismo-Electromagnetic Satellite (CSES). By applying sliding interquartile range method electron de...

Multifractal modeling of geochemical map data can help to explain the nature of frequency distributions of element concentration values for small rock samples and their spatial covariance structure. Useful frequency distribution models are the lognormal and Pareto distributions which plot as straight lines on logarithmic probability and log-log paper, respectively. The model of de Wijs is a sim...

The Hetaoping ore district in Baoshan City, Yunnan Province, is one of the major localities Pb-Zn polymetallic skarn deposits China, where geophysical and geochemical surveys play an important role exploring mineral resources. Based on exploration prospecting carried out at periphery deposit, this study proposed aero-ground joint method to determine metallogenic model distal skarns district, ac...

Hydrocarbon leakage into the environment has large economic and environmental impact. Traditional methods for investigating seepages and their resulting pollution, such as drilling, are destructive, time consuming and expensive. Remote sensing is an efficient tool that offers a non-destructive investigation method. Optical remote sensing has been extensively tested for exploration of onshore hy...

We present a comprehensive geochemical data set for the most recent volcanics from the Mariana Islands, which provides new constraints on the timing and nature of fluxes from the subducting slab. The lavas display many features typical of island arc volcanics, with all samples showing large negative niobium anomalies and enrichments in alkaline earth elements and lead (e.g., high Ba/La and Pb/C...

The coal-bearing sequences of the Late Permian in southwest China are enriched critical elements Sc, V, Co, Ni, Cu, Zn, Nb, Ta, Zr and Hf. Ascertaining conditions basis for enrichment this area is very important to support metal demands China. In study, we analyzed concentrations elemental compositions coal samples collected from Guishan coalfield eastern Yunnan, results show that C4-Upper seam...
