CanaddBritish Columbia Mineral Development Agreement, this area was selected for more detailed analysis than presently available. During the 1986 field season fieldwork was centred on the Cowichan Lake area (Figures 3-9-1 and 3-9-21, Access in the area is provided by an extensive network of logging roads in various states of upkeep. Roadcuts provide most ofthe exposure for mapping; rock units a...

BACKGROUND In the summer of 2015, hundreds of wildfires burned across the state of Alaska, and consumed more than 1.6 million ha of boreal forest and wetlands in the Yukon-Koyukuk region. Mapping of 113 large wildfires using Landsat satellite images from before and after 2015 indicated that nearly 60% of this area was burned at moderate-to-high severity levels. Field measurements near the town ...

Presently, little is known about the potential health effects of mineral particles other than asbestos and quartz. In this study, a human epithelial lung cell line (A549), primary human small airway epithelial cells (SAECs) and primary rat type 2 (T2) cells were exposed to stone quarry particles of two size fractions (<10 and <2.5 microm) from nine different rock samples. The ability to induce ...

Airborne geophysical systems have been in use since 1943 (Hildenbrand et al., 1990). These systems used airborne magnetometers for submarine detection and geophysical mapping. Airborne electromagnetic systems were introduced in the 1950s (Barringer et al., 1990) for mineral exploration. These early magnetic and electromagnetic systems were mounted on fixed wing aircraft. In the 1960s helicopter...

At the most fundamental level, interand intramolecular forces delineate the interface between a microorganism and a mineral surface. A new technique, termed biological force microscopy (BFM), is described that can be used to directly probe the dynamics of the mineral–microbe interface. BFM quantiŽ es attractive and repulsive forces in the nano-Newton range between living microbial cells and min...

Sedimentary rocks contain a unique record of the evolution Earth system. Deciphering this requires robust understanding identity, origin, composition, and post-depositional history individual constituents. Petrographic analysis informed by Scanning Electron Microscope - Energy Dispersive Spectroscopy (SEM-EDS) mineral mapping can reveal morphology petrological context each imaged grain, making ...

The Dolatabad area located in SE Iran is a well-endowed terrain owning several chromite mineralized zones. These chromite ore bodies are all hosted in a colored mélange complex zone comprising harzburgite, dunite, and pyroxenite. These deposits are irregular in shape, and are distributed as small lenses along colored mélange zones. The area has a great potential for discovering further chromite...
