A Summary of FieldActivities and Current Research. The new name reflects expansion of thescope of this publication to include reports that cover the entire spectrum of work carried out by the Geological Branch. Reports on the two main inventory files of the Branch, MIITFILE and COALFILE, areincluded for the first time. The main aim IO€ the publicationremains unchanged; to acquaint the interested public with preliminary results of fieldwork of geologists of theGeological Branch as soon as possible after the field season. The 19R4 field program, like 1983, was reduced in corparison to previous years as British Columbia entered the second year of fiscal restraint. Tilose geologists in the field had shortened field seasons and none had more than one fieldassistant. others were confinedto the office, completing long-term projects. Thisedition has a three-sectionformat; within each section, reports are sequencedaccording to NTS. The Project andApplied Geology section includes reports on field mappingand propertyexaminations conducted by bothProject and District Geologists. The ResourceData section consists of reports on MINFILE, COALFILE, landuse issues, and assessmentrc?ports. The Other Investigations section consists of fourpapers submitted by researchersat the University of British Columbia;each represents a cooperative project.

  • Holocene Tephras in Lake Cores from Northern British Columbia, Canada
    935 Holocene tephras in lake cores from northern British Columbia, Canada Thomas R. Lakeman, John J. Clague, Brian Menounos, Gerald D. Osborn, Britta J.L. Jensen, and Duane G. Froese Abstract: Sediment cores recovered from alpine and subalpine lakes up to 250 km apart in northern British Columbia con- tain five previously unrecognized tephras. Two black phonolitic tephras, each 5–10 mm thick, occur within 2–4 cm of each other in basal sediments from seven lakes in the Finlay River – Dease Lake area. The upper and lower Finlay tephras are slightly older than 10 220 – 10 560 cal year B.P. and likely originate from two closely spaced eruptions of one or two large volcanoes in the northern Cordilleran volcanic province. The Finlay tephras occur at the transition between deglacial sediments and organic-rich postglacial mud in the lake cores and, therefore, closely delimit the termination of the Fraser Glaciation in northern British Columbia. Sediments in Bob Quinn Lake, which lies on the east edge of the northern Coast Mountains, contain two black tephras that differ in age and composition from the Finlay tephras. The lower Bob Quinn tephra is 3–4 mm thick, basaltic in composition, and is derived from an eruption in the Iskut River volcanic field about 9400 cal years ago. The upper Bob Quinn tephra is 12 mm thick, trachytic in composition, and probably 7000–8000 cal years old. A fifth tephra occurs as a cryptotephra near the top of two cores from the Finlay River area and is correlated to the east lobe of the White River tephra (ca.

Declining metal prices resulted in the closure of the last producing mine in 1957, but in recent years extensive geophysical and geochemical surveys have been made by several major exploration com­ panies and new prospects have been discovered.

  • The Genesis of Zeolites

Subsequently, a description and interpretation is given of the geological environments where zeolites crystallize in nature.

  • Chemical Composition of Ferrierite WILLIAM S. WISE 93/06
    American Mineralogist, Volume 61, pa ges 60-66, 1976 Chemical composition of ferrierite WILLIAM S. WISE Department of Geological Sciences, University of California Santa Barbara, California 93/06 AND R. W. TSCHERNICH 532 Avenue A, Snohomish, Washington 98920 Abstract Ferrierite specimens from localities at Altoona, Washington; Silver Mountain, Alpine County, California; and Pinaus Lake, Monte Lake, and Francois Lake, British Columbia, have been analyzed by microprobe methods. These new analyses are combined with available data to delineate the compositional range for this zeolite. The frame work composition ranges from (Al7•5Si27 5072) to (Al,Sia,072). The a cell dimension varies linearly with the Si content. There are between 3 and 5 exchangeable cations (univalent and divalent) per unit cell of 72 oxygens, but with wide variations; the amount of univale11t ions ranges from 21 to 85 percent. There is no clear parititioning of the univalent ions, as the Na/(Na+K) ratio is highly variable. Mg is clearly fractionated in all ferrierites (Ca/(Ca + Mg) < 0.40), regardless of the amount of divalent ions. The highest known amounts of BaO (2.54%) and SrO (0.40%) are in the Silver Mountain ferrierite. Associated zeolites commonly include clinoptilolite or heulandite, although mordenite and dachiardite also occur with ferrierite at Altoona. The broad compositional range of ferrierite indicates that it can crystallize from solutions with a wide variety of alkali and alkaline earth cations, none of which are essential to the zeolite. If present, Mg ions are fractionated into the zeolite. Ferrierite crystallizes in response to high silica activities. However, to account for the range in silica contents, the a810, must be coupled with other variables, such as temperature or aH,o, in order to prevent crystallization of other high silica zeolites.

The Meager avalanches. In 1975, increased fumarolic activity in the Sherman Crater area caused concern that an eruption might be imminent. Additional monitoring Anahim Volcanic Belt trends easterly across central British Columbia and is Garibaldi probably related to a mantle hot spot. The Stikine Volcanic Belt forms a broad equipment was installed and several geophysical surveys were conducted to try to zone of volcanoes in northwestern British Columbia and the southern Yukon. These Baker (Washington) detect the movement of magma. The level of Baker Lake was lowered and people volcanoes are probably related to shear along the Queen Charolette transform were restricted from the area due to concerns that an eruption- induced debris fault to the west.
