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.

A number of small lead/zinc occurrences are hosted by grey plant-debris-rich sandstone of the Late Carboniferous of the Canadian Maritimes. This paper documents field observations on the geological environment of one of these occurrences at Meadowville, Nova Scotia. The aim of the paper is to comment on the possible extent of this occurrence, to provide field criteria for exploration for Carboniferous sandstone lead/zinc deposits, and to provide data for genetic modelling of this type of deposit.

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.
