  • Handbook of Iron Meteorites, Volume 2 (Canyon Diablo, Part 2)
    Canyon Diablo 395 The primary structure is as before. However, the kamacite has been briefly reheated above 600° C and has recrystallized throughout the sample. The new grains are unequilibrated, serrated and have hardnesses of 145-210. The previous Neumann bands are still plainly visible , and so are the old subboundaries because the original precipitates delineate their locations. The schreibersite and cohenite crystals are still monocrystalline, and there are no reaction rims around them. The troilite is micromelted , usually to a somewhat larger extent than is present in I-III. Severe shear zones, 100-200 J1 wide , cross the entire specimens. They are wavy, fan out, coalesce again , and may displace taenite, plessite and minerals several millimeters. The present exterior surfaces of the slugs and wedge-shaped masses have no doubt been produced in a similar fashion by shear-rupture and have later become corroded. Figure 469.

This kind of material is believed to represent shock­ annealed fragments of the impacting main body. Since the fragments have not had a very long flight through the atmosphere, well developed fusion crusts and heat-affected rim zones are not expected to be present. The energy responsible for bulk reheating of the small masses to about 600° C is believed to have come from the conversion of kinetic to heat energy during the impact and fragmentation.

  • Quicksilver Deposits of Steens Mountain and Pueblo Mountains Southeast Oregon
    Quicksilver Deposits of Steens Mountain and Pueblo Mountains Southeast Oregon GEOLOGICAL SURVEY BULLETIN 995-B A CONTRIBUTION TO ECONOMIC GEOLOGY QUICKSILVER DEPOSITS OF STEENS MOUNTAIN AND PUEBLO MOUNTAINS, SOUTHEAST OREGON By HOWEL WILLIAMS and ROBERT R. The object of this survey was to examine the quicksilver deposits with the hope of locating large tonnages of low-grade ore. The deposits occur in the south-central part of Harney County and are more than 100 miles from either Burns, Oreg., or Winuemucca, Nev., the nearest towns. The region is sparsely settled by stockmen; Fields, Denio, and Andrews are the only settlements. The range consisting of Steens Mountain and Pueblo Mountains is a dissected fault block, 90 miles long in a north-south direction and as much as 25 miles wide, tilted gently to the west. Pre-Tertiary rnetarnorphic and plutonic rocks occur at the southern end, but most of the block consists of Pliocene volcanic rocks. The major boundary faults on the east side of the range are concealed by alluvium. Minor northwestward-trending faults branch from them, their throws diminish­ ing toward the crest of the range; other minor fractures occur near, and parallel to, the mountain front. The quicksilver lodes were formed in and along these subsidiary fractures. The lodes occur in a more or less continuous belt just west of the eastern front of the range. They are steeply dipping and arranged in subparallel clusters, commonly standing out as resistant siliceous ribs against the softer kaolinized rocks that flank them. The lodes were formed in two hydrothermal stages, the first producing the reeflike masses of chalcedony and quartz with their halos of limonitic and calcitic clays and the second introducing silica and barite along with sulfides of iron, copper, and mercury.
