The analysis of sanshan island based on constrained magnetization vector inversion.

Gold ores are important strategic key mineral resource in China. The Sanshan Island area produces gold ores, in which the magmatic activity becomes the heat source for the activation of gold-bearing fluids, and the widely developed fracture structure provides the channel and spatial structure for gold transport and enrichment. Therefore, it is an important direction to utilize the inversion method to portray the distribution of fractures and intrusive rocks.

Improved adaptive regularization for simulated annealing inversion of transient electromagnetic.

Geophysical inversion usually involves ill-posed problem. Regularization is the most commonly used method to mitigate this problem. There are many regularization parameter selection methods, among which the adaptive regularization method can automatically update parameters during iteration, reducing the difficulty of parameter selection.
