View Resource Peering into the Crystal Fabric of Rocks

This Oceanus article describes the work of Greg Hirth, a geologist studying rock deformation and crystallography. It discusses how rocks deform as a function of pressure and heat (called rheology) and includes a short section about the possibility of microbial life in the heat and pressure-induced cracks between crystals. Hyperlinks to related articles are contained within the text of the...

View Resource Cryptoendolith Communities in Antarctic Dry Valley Region Sandstones: Potential Analogues of Martian Life-Forms

This Lunar and Planetary Science article provides information about cryptoendolithic life (microbes living within rocks on the Earth's surface) in Antarctic sandstones. The purpose of the study was to use chemical and isotopic methods to determine what influence the cryptoendoliths have on the rocks they live in. These cryptoendoliths are predominantly lichen that live in the pores between sand...

View Resource The Role of Micro-Organisms in Acid Rock Drainage

This reference site explains the role of microbes in acid rock drainage. Topics include the sulfur cycle, the role of microorganisms in the sulfur cycle, natural oxidation in the sulfur cycle, natural reduction in the sulphur cycle, other microorganism reactions in the sulphur cycle, and references. The reference includes a scientific illustration of the sulphur cycle, images of...

View Resource Coping with Contamination

This magazine article features an interview with Mars Analog Research and Technology Experiment (MARTE) scientist Carol Stoker. In this third session of the four-part series, Stoker describes how the MARTE team avoids contaminating their drill-core samples. Her team is drilling into the pyrite subsurface of Spain's Rio Tinto in search for microbes existing in an iron-sulfur-based energy system,...

View Resource Seismic Reflection Imaging of Impact-Induced Faulting and Deformation at Upheaval Dome, Canyonlands National Park, Utah

This report describes a study in which seismic profiling was used to re-interpret the origin of Upheaval Dome, Utah, a geologic structure that was originally thought to be the results of a salt diapir, but which the authors believe may be the remains of an ancient impact structure. ABSTRACT: Seismic imaging techniques applied to a reflection survey show two phases of faulting and deformation...
