Introduction: Venus as a probable single-plate planet [1] has a unique set of volcano-tectonic features. The enigmatic circular structures, coronae are of great interest in particular. The corona definition does also include other concentric features known as the “arachnoids” [2], but it does not elaborate on the details of the concentric volcano-tectonic structures. In several cases, coronae a...

In this article, a new technique for features extraction from SAR interferograms is presented. The technique combines the properties of auto-associative neural networks with those of more traditional approaches such as discrete Fourier transform or discrete wavelet transform. The feature extraction is chained to another neural module performing the estimation of the fault parameters characteriz...

A detail field and microscopic characteristics of Malayer Plutonic Rocks (162-187Ma), west of Iran, are discussed in details to evaluate relationships between deformation and pluton emplacement. The studied rocks were injected into the slate, phyllite and schists of so called "Hamadan phyllites and slates" in the Sanandaj-Sirjan zone. Studies have shown that there is a continuity from magmatic ...

The western part of N 2 area is located at the tectonic high point D oil field, with faults cut into each other, staggered distribution and complex fracture structure. In this paper, based on 3D seismic interpretation, research fault geometry, kinematic characteristics, deformation period grade division are systematically carried out. quantitative discriminatory criteria plane segmental growth ...

1 Lobate scarps, thought to be the surface expression of large thrust faults, are the 2 most spectacular contractional tectonic features visible on Mercury. Most lobate scarps 3 follow a general and relatively simple pattern, with a roughly arcuate or linear form in plan 4 view, and an asymmetric cross section characterized by a steeply rising scarp face and a 5 gently declining back scarp. In ...

INTRODUCTION Recent volcanic activity of Io generally does not produce conical mountains. Instead, their lava run out in thin, long flows. Volcanic centers are typically large, deep calderas cut into the interpatera plains. Bright lava flows on Io can mostly be associated with sulfur lavas, with no visible escarpments that would indicate higher viscosity material. From temperature measurements ...
