The Malayer plutonic complex: field geology, petrography and geochemical interpretation
The geochemical signatures like discordant variation of major and trace elements among felsic-intermediate and basic rocks and mafic enclaves of Malayer region on binary variation plots, decreasing values of FeOt, TiO2, MgO, MnO and CaO accompanied with increasing of SiO2 content from basic to felsic rocks, and decreasing Ni, Cr and Co with increasing SiO2 are considered as indications of mag...
متن کاملGreat challenges in structural geology and tectonics
Successful scientific theories provide theoretical understanding for reliable deterministic or probabilistic forecasting of events. In the past decades the volume of data obtained within the fields of structural geology and tectonics has increased enormously, but the theoretical understanding of the processes that generate these data has not advanced at the same rate. For example, after decades...
متن کاملGeology and Mineral Potential of the Warner Pass Map Sheet*
The Warner Pass map area is located 185 kilometres north of Vancouver on the northeastern margin of the Coast Mountains. It covers an area of 980 square kilometres within the Chilcotin Range, and is characterized by rugged mountains and glaciated U-shaped valleys; elevations vary from IS00 metres to over 3000 mctres, with a treeline at about 1800 metres. The sheet was mapped at a scale of 1:20 ...
متن کاملA Sketching Tool for Illustrative Structural Geology
We describe a sketch-based system for constructing an illustrative visualization of the subsurface. An intuitive and rapid modelling tool is defined, which takes as input user’s strokes and creates a 3D layer-cake model of the earth. Our tool enables users to quickly express and communicate their ideas directly using a 3D model. For sketching, we have created geometric operators that capture th...
متن کاملMap Interpretation in Dynamic Environments
In this paper we present a navigation system for a mobile robot that is capable of operating in dynamic environments. Mapbuilding is based on landmark detection , with landmarks being established through a process of self-organisation of the robot's sensory data. The resultant map can then be used to determine, and subsequently follow, arbitrary paths through the environment. The results of sev...
