Oxygenic bismuth minerals in the NE part of the Karkonosze pluton (West Sudetes, SW Poland). Acta Geologica Polonica, 68 (4), 537–554. Warszawa. The study presents fifteen oxygen-bearing secondary minerals of bismuth from the north-eastern part of the Variscan Karkonosze granitoid pluton in the northern zone of the Bohemian massif. The minerals were inves- tigated by optical, electron microprobe, classic chemical, XRD, IR absorption and fluid inclusion methods. The late, very low temperature epithermal solutions most probably caused formation of sillénite, kusachiite, bismoclite, bismutite, beyerite, kettnerite, pucherite, schumacherite, namibite and eulytite. Solutions dominated by supergene (meteoric) waters were the parents for bismite, russellite, koechlinite, ximengite and walpurgite. The paper also contains information on early research on the investigated minerals. Key words: Karkonosze granitoid pluton; Bismuth minerals; Secondary minerals; Oxidation; Vein; Pegmatite.

MONTANA DEPARTMENT OF ENVIRONMENTAL QUALITY, and TINTINA MONTANA INC.; Defendants. INTRODUCTION 1. Plaintiffs Montana Trout Unlimited, Montana Environmental Information Center, Trout Unlimited, Earthworks, and American Rivers (collectively, “Plaintiffs”) challenge the Montana Department of Environmental Quality’s (“DEQ”) approval of Tintina Montana Inc.’s (“Tintina”) permit application for the Black Butte Copper Mine, a major copper mining project proposed in the Smith River watershed of west-central Montana. The Smith River is one of Montana’s premier recreational rivers due to its spectacular natural beauty and abundant wild trout populations. 2. Tintina’s proposed mine would excavate about 440 tons of concentrated copper ore every day in the Smith River watershed. Over the life of the project, these mining activities would generate an estimated 12.9 million tons of tailings and nearly one million tons of waste rock and pollute waters within the Smith River watershed with metals and acid-generating minerals that are harmful or lethal to aquatic life. 3. DEQ is the agency charged with permitting mining activity under the Metal Mine Reclamation Act (“MMRA”), MCA § 82-4-301 et seq., and evaluating the environmental impacts of proposed mining activities under the Montana Environmental Policy Act (“MEPA”), MCA § 75-1-101 et seq.
  • Kamloops TSA - Forest Health Strategy

    Kamloops TSA - Forest Health Strategy

    Kamloops TSA - Forest Health Strategy Thompson Rivers Forest District April 2017 Executive Summary The Kamloops TSA Forest Health Strategy has for the most part not been changed for this year. There have been minor edits, as well as some additions. It is expected that over the next few years, that there will be more information added with respect to; Stand Establishment Decision Aids, strategies for pests in young stands, stocking standards related to forest health factors and climate change adaptation strategies. The changes of note this year are: • New Root disease guidance Document Update on Bark Beetles in Kamloops TSA: • Areas affected by Western balsam bark beetle have dropped to less than half of 2016 levels resulting in 59,730 hectares infested. The decline is due to lower red attack rates, with stands in the northern portion of the TSA, around Dunn Peak, Trophy Mountain, and Wells gray Park and the upper North Thompson being the most affected. • Spruce beetle – attack levels remain high, with 9,770 hectares identified, the largest new infestation moving into uninfested stands in Wells Gray Park around Kostal Lake, McDougall Lake, and the west arm of Murtle Lake, Angus Horn Creek and the Upper Clearwater River. • Douglas fir beetle – the area affected by Douglas fir beetle more than doubled, to 3,100 hectares in 362 patches and 1,290 smaller spot infestations. The attack is widespread across the southern portion of the TSA with significant red attack in the Wells Gray Park, Barriere River, Adams Lake and Pinantan Lake areas. Douglas fir beetle is anticipated to build in fire damaged trees along the margins of the Elephant Hill, Thuya Lakes and Dunn Lake fires where there is variable burn severity and low intensity ground fires.
