Abstract Geophysical problems often involve Lagrangian particles that follow surrounding flows and record information about the system, such as the pressure and temperature path recorded in metamorphic rocks. These Lagrangian particles can be useful for constraining unknown parameters, such as their sources and the thermal and flow processes of the ...

Deep‐Learning‐Enhanced Electron Microscopy for Earth Material Characterization
Abstract Rocks, as Earth materials, contain intricate microstructures that reveal their geological history. These microstructures include grain boundaries, preferred orientation, twinning and porosity, holding critical significance in the realm of the energy transition.

Abstract Lithological thin‐section image classification is crucial in geology. Traditional manual methods rely on expert experience, being subjective and time‐consuming. Convolutional neural network (CNN)‐based automated classification has potential but is less effective with more rock types and limited training data, restricting its applications.

Abstract The study of the mineralization dynamics of the Cu–Au–Mo deposit at the northern margin of the North China Craton and the southeastern margin of the Central Asian Orogenic Belt is important for understanding metallogenic settings. We calculated the crustal oxide content in heterogeneous systems using crustal temperature, seismic wave velocity (

Key Points An analytical strategy for determining boron isotope ratios in Ca‐amphiboles using LA‐MC‐ICP‐MS is presented. Accurate δ11B results can be achieved using the USGS BHVO‐2G glass as the calibrating reference material. Two proposed Ca‐amphibole RMs exhibit good homogeneity with δ11B intermediate measurement precision of 2.86‰ and 3.96‰ (2s ...
