Book Description
The Upper Triassic sections outcropping on the Queen Charlotte Islands contain outstanding successions of conodont and radiolarian microfossils. This report focuses on the successions about the Carnian-Norian boundary at several key localities. This boundary may coincide with an interval of significant change in global fauna and flora, particularly in terrestrial habitats. The purpose of the study reported is to demonstrate faunal change that may potentially be used in global correlation and definition of the Carnian-Norian boundary, and thus contribute towards the resolution of historical events that date from that time. The report summarizes the radiolarian change within the boundary interval identified primarily by conodonts but supplemented by some molluscan data.

Book Description
A well-exposed section about 250 metres wide below the high water line of the Jennings River, Teslin Lake map area in northern British Columbia shows part of the Teslin Fault and provides an opportunity to constrain the fault's kinematic history by direct ground observations. This report describes preliminary structural observations of this section of the Teslin Fault, including the rock types involved, mylonitic & ultramylonitic structures, and deformation. Indications of two main episodes of shearing are discussed.

Book Description
The mission of the U.S. Geological Survey (USGS) Water Resources Discipline is to provide the information and understanding needed for wise management of the Nation's water resources. Inherent in this mission is the responsibility of collecting data that accurately describe the physical, chemical, and biological attributes of water systems. These data are used for environmental and resource assessments by the USGS, other government agencies and scientific organizations, and the general public. Reliable and quality-assured data are essential to the credibility and impartiality of the water-resources appraisals carried out by the USGS.
