    ACT A POLONICA Vol. 25 No. 3-4 VLASTA ZUKALOVA STROMATOPOROIDS IN THE DEVONIAN CARBONATE COMPLEX IN MORAVIA (CZECHOSLOVAKIA) ZUKALOVA, v.: Stromatoporoids in the Devonian carbonate complex in Mo­ ravia (Czechoslovakia). Acta Palaeont. Polonica, 25, 3/4, 671-679, December 1981. Studies of the Paleozoic rocks in Moravia based on abundant drillings reveal the extent of the Devonian reefs (s.!.) beneath the Carpathia~ Flysh Belt and Neogene foredeeps. Reef limestones (rich mainly in stromatoporoids) are re­ stricted to the platform part of the sedimentary basin. A 'gradual transgression reached this area during the Givetian and Frasnian having its culmination in the Early Frasnian. Development of reef limestones in Moravia ceased at the Frasnian/Famennian boundary. Key W 0 r d s: Stromatoporoidea, stratigraphy, Devonian, Czechoslovakia. Vlasta Zukalova. Ostfedni Ostav Geo!ogicIQ/, 60200 Brno, Leitnerova 22, Cze­ choslovakia. Received: September 1979. The Paleozoic' sedimentary basin is bounded on the west by meta­ morphosed crystalline rocks. Paleozoic deposits are covered by the Carpa­ thian nappes and the Neogene foredeep fillings on the south and south­ east, while they extend into Polish territory on the north and northeast. The Silurian graptolite shales occurring near the village of Stinava are the most ancient sediments for which there is paleontological evidence in Moravia (Bollcek 1935). They give evidence of the earliest marine trans­ gression over Moravia. During Paleozoic time, deep sea conditions pre­ vailed in this area where mainly shales with subordinate limestone inter­ calations were deposited. The Lower Devonian (Siegenian) transgression took place over a re­ stricted area. Relics of fauna in the quartzites are known at the villages of Zlate Horyand Vrbno.

  • L'.3350 Deposmon and DISSOLUTION of the MIDDLE DEVONIAN PRAIRIE FORMATION, Williston BASIN, NORTH DAKOTA and MONTANA By
    l'.3350 DEPOsmON AND DISSOLUTION OF THE MIDDLE DEVONIAN PRAIRIE FORMATION, WilLISTON BASIN, NORTH DAKOTA AND MONTANA by: Chris A. Oglesby T-3350 A thesis submined to the Faculty and the Board of Trustees of the Colorado School of Mines in partial fulfillment of the requirements for the degree of Master of Science (Geology). Golden, Colorado Date f:" /2 7 /C''i::-- i ; Signed: Approved: Lee C. Gerhard Thesis Advisor Golden, Colorado - 7 Date' .' Samuel S. Adams, Head Department of Geology and Geological Engineering II T-3350 ABSTRACf Within the Williston basin, thickness variations of the Prairie Formation are common and are interpreted to originate by two processes, differential accumulation of salt during deposition, and differential removal of salt by dissolution. Unambiguous evidence for each process is rare because the Prairie/Winnipegosis interval is seldom cored within the U.S. portion of the basin. Therefore indirect methods, utilizing well logs, provide the principal method for identifying characteristics of the two processes. The results of this study indicate that the two processes can be distinguished using correlations within the Prairie Formation. Several regionally correlative upward-brining, and probably shoaling-upward sequences occur within the Prairie Formation .. Near the basin center, the lowermost sequence is transitional with the underlying Winnipegosis Formation. This transition is characterized by thinly laminated carbonates that become increasingly interbedded with anhydrites of the basin-centered Ratner Member, the remainder of the sequence progresses up through halite and culminates in the halite-dominated Esterhazy potash beds. Two overlying sequences also brine upwards, however, these sequences lack the basal anhydrite and instead begin with halite and culminate in the Belle Plaine and Mountrail potash Members, respectively.
