  • Geology and Hydrothermal Alteration of the Duobuza Goldrich Porphyry
    doi: 10.1111/j.1751-3928.2011.00182.x Resource Geology Vol. 62, No. 1: 99–118 Thematic Articlerge_182 99..118 Geology and Hydrothermal Alteration of the Duobuza Gold-Rich Porphyry Copper District in the Bangongco Metallogenetic Belt, Northwestern Tibet Guangming Li,1 Jinxiang Li,1 Kezhang Qin,1 Ji Duo,2 Tianping Zhang,3 Bo Xiao1 and Junxing Zhao1 1Key Laboratory of Mineral Resources, Institute of Geology and Geophysics, CAS, Beijing, 2Tibet Bureau of Geology and Exploration, Lhasa, Tibet and 3No. 5 Geological Party, Tibet Bureau of Geology and Exploration, Golmu, China Abstract The Duobuza gold-rich porphyry copper district is located in the Bangongco metallogenetic belt in the Bangongco-Nujiang suture zone south of the Qiangtang terrane. Two main gold-rich porphyry copper deposits (Duobuza and Bolong) and an occurrence (135 Line) were discovered in the district. The porphyry-type mineralization is associated with three Early Cretaceous ore-bearing granodiorite porphyries at Duobuza, 135 Line and Bolong, and is hosted by volcanic and sedimentary rocks of the Middle Jurassic Yanshiping Formation and intermediate-acidic volcanic rocks of the Early Cretaceous Meiriqie Group. Simultaneous emplacement and isometric distribution of three ore-forming porphyries is explained as multi-centered mineralization generated from the same magma chamber. Intense hydrothermal alteration occurs in the porphyries and at the contact zone with wall rocks. Four main hypogene alteration zones are distinguished at Duobuza. Early-stage alteration is dominated by potassic alteration with extensive secondary biotite, K-feldspar and magnetite. The alteration zone includes dense magnetite and quartz-magnetite veinlets, in which Cu-Fe-bearing sulfides are present.

  • Baker County Community Sensitivity and Resilience
    Baker County Community Sensitivity and Resilience This section documents the community’s sensitivity factors, or those community assets and characteristics that may be impacted by natural hazards, (e.g., special populations, economic factors, and historic and cultural resources). It also identifies the community’s resilience factors, or the community’s ability to manage risk and adapt to hazard event impacts (e.g., governmental structure, agency missions and directives, and plans, policies, and programs). The information in this section represents a snapshot in time of the current sensitivity and resilience factors in the community when the plan was developed. The information documented below, along with the findings of the risk assessment, should be used as the local level rationale for the risk reduction actions identified in Section 6 – Mission, Goals, and Action Items. The identification of actions that reduce a community’s sensitivity and increase its resilience assists in reducing the community’s overall risk, or the area of overlap in Figure G.1 below. Figure G.1 Understanding Risk Source: Oregon Natural Hazards Workgroup, 2006. Northeast Oregon Natural Hazard Mitigation Plan Page G-1 Community Sensitivity Factors The following table documents the key community sensitivity factors in Baker County. Population • Baker County has eight distinct geographic populations, as well as eight unincorporated communities. Incorporated cities are: Baker City, Greenhorn, Haines, Halfway, Huntington, Richland, Sumpter, and Unity. Unincorporated communities include: Durkee, Hereford, Pinetown, McEwen, Keating, Sparta, New Bridge, and Oxbow. Communities are geographically dispersed with little communication or interconnection. If communities need to be warned of an event, or require disaster assistance, distance and dispersal will be communication barriers.

The Mountain of a Thousand Holes Shipwreck Traditions and Treasure Hunting on Oregon’s North Coast CAMERON LA FOLLETTE, DENNIS GRIFFIN, AND DOUGLAS DEUR EURO-AMERICANS in coastal communities conflated and amplified Native American oral traditions of shipwrecks in Tillamook County, increasingly focusing the stories on buried treasure. This focus led to a trickle, and then a procession, of treasure-seekers visiting the northern Oregon coast, reach- ing full crescendo by the mid to late twentieth century. The seekers’ theo- ries ranged from the fairly straightforward to the wildly carnivalesque, with many bizarre permutations. Neahkahnie Mountain and its beaches became the premier treasure-hunting sites in Oregon, based on the mountain’s prominence in popular lore, linked to unverified stories about the wreck of a Spanish ship.

  • Silver Enrichment in the San Juan Mountains, Colorado
    SILVER ENRICHMENT IN THE SAN JUAN MOUNTAINS, COLORADO. By EDSON S. BASTIN. INTRODUCTION. The following report forms part of a topical study of the enrich­ ment of silver ores begun by the writer under the auspices of the United States Geological Survey in 1913. Two reports embodying the results obtained at Tonopah, Nev.,1 and at the Comstock lode, Virginia City, Nev.,2 have previously been published. It was recognized in advance that a topical study carried on by a single investigator in many districts must of necessity be less com­ prehensive than the results gleaned more slowly by many investi­ gators in the course of regional surveys of the usual types; on the other hand the advances made in the study of a particular topic in one district would aid in the study of the same topic in the next. In particular it was desired to apply methods of microscopic study of polished specimens to the ores of many camps that had been rich silver producers but had not been studied geologically since such methods of study were perfected. If the results here reported appear to be fragmentary and to lack completeness according to the standards of a regional report, it must be remembered that for each district only such information could be used as was readily obtainable in the course of a very brief field visit. The results in so far as they show a primary origin for the silver minerals in many ores appear amply to justify the work in the encouragement which they offer to deep mining, irrespective of more purely scientific results.

  • Structural Diagenesis in Carbonate Rocks As Identified in Fault

Based on the examination of core and sample thin section data, we deciphered the diagenetic parasequence and their fault controls for Ordovician carbonates in the northern Tarim intracratonic basin in NW China (Halahatang area). In contrast to the uniform nature of diagenesis observed in country rocks, there is a relatively complicated style of compaction and pressure solution, multiple fracturing, and cementation and dissolution history along the carbonate fault damage zones. The relative paragenetic sequence of the structure related diagenesis suggests three cycles of fracture activities, following varied fracture enlargement and dissolution, and progressively weaker calcite cementation. These processes of structure related diagenesis are constrained to the fault damage zones, and their variation is affected by the fault activities.

  • MINING in BAKER COUNTY, 1861 to 1959* by Norman S
    Vol.21, No.3 THE ORE.- BIN 21 March 1959 Portland, Oregon STATE OF OREGON DEPARTMENT OF GEOLOGY AND MINERAL INDUSTRIES Head Office: 1069 State Office Bldg., Portland I, Oregon Telephone: CApitol 6-2161, Ext. 488 Field Offices 2033 First Street 239 S. E. "H"Street Baker Grants Pass *************************** MINING IN BAKER COUNTY, 1861 to 1959* By Norman S. Wagner** Introduction Baker County mining began with the discovery of gold in 'Griffin Gulch in 1861. This and the develop­ ment which followed at Auburn represent gold mining at its historic best. Since 1861, much water has flowed down the sluice boxes with respect to mineral resource development within the county. As a result, the dis­ covery story is left for historians to tell, and the following paragraphs are devoted to the high points of the many kinds of mining endeavors that occurred in Baker County between 1861 and 1959. Hydraulic and sluicing operations All of the earlier placer operations have one thing in common with Griffin Gulch and Auburn. This is that they were carried out by means of ground sluicing and hydraul icking, using generous amounts of hand labor. These means of handl ing placer ground continued in exclusive use throughout the first forty years of Baker County mining history. It wasn't until the present century that the more familiar bucket-line dredges and other kinds of mechanized digging and washing plants made their appearance. Even yet the old methods are still employed on a small scale in circumstances where ground conditions permit. The Rye Valley placers on Dixie Creek represent a notable example of an early discovery made shortly after 1862.
