Description:
Abstract:
Geochemical analyses of authigenic carbonates, bivalves, and pore fluids were performed on samples collected from seep fields along the Queen Charlotte Fault, a right lateral transform boundary that separates the Pacific and North American tectonic plates. Samples were collected using grab samplers and piston cores, and were collected during three different research cruises in 2011, 2015, and 2017.
Purpose:
These samples were collected and analyzed as part of an effort to determine the origin and occurrence of venting along the Queen Charlotte Fault.
Supplemental_Information:
Samples from 2011 and 2015 were collected by Dr. Vaughn Barrie from Pacific Geoscience Centre of the Geological Survey of Canada during their research cruises (2011002PGC and 2015004PGC).
Additional information about the USGS field activity from which the 2017 samples were collected is available online at: https://cmgds.marine.usgs.gov/fan_info.php?fan=2017-652-FA
