Horizontally occurring layers are depicted most simply on geological maps. The borders between layers are at an equal elevation, and their drawing on the map repeats the curves of the relief horizontals (see Figure 1). Where layers occur on a slope it becomes more difficult to depict them bec...
An overview of the geology of the Eastern Karakoram is also presented and includes a discussion of the architecture and kinematics of the central segment of the Karakoram fault. The construction of the map has aided our understanding of the initiation and evolution of the Karakoram fault and of ...
UK-based mineral exploration is relevant to the growing interest of critical mineral supplies (Walton et al., 2021). The Geochemical Baseline Survey of the Environment (G-BASE) run by the British Geological Survey (BGS) contains data on stream sediment, water, and soil geochemistry. It also ...

Considering the relationship between the distribution density of the disaster in different classes of condition factors and in the study area, the Wi-index can be calculated by relative weights of different levels in each condition factor and presented in a susceptibility map. This method applies to...
