Charakterisierung der Veränderlichkeit von Lagerstättenmerkmalen durch Anwendung von Zufallsfunktionen. (Description of alterability of deposit parameters by means of application of random functions)
the regular component of the parameter alterability by mathematical ways substantial characteristics of the geological structure were elaborated, which made it possible to explore and evaluate deposits according to geological conditions. (HL).
At the example of a vein deposit, the alteribility of deposit parameters (metal content, thickness) is analysed by means of applying the theory of random functions and the character of their parameters is described quantitatively. Deriving
Geological investigations in the centre of Haarlem (The Netherlands) and the development of the river Spaarne
The Spaarne river, exists since the early Subboreal and drains into the former IJ estuary. Its main sand deposits date from the early Subatlantic, other deposits from after the beginning of the Christian era. Sands of medium grain size are obviously
Modern deposits, quasi-deposits and some Holocene sequences in the Southern Bight, North Sea in The Quaternary and Tertiary geology of the Southern Bight, North Sea.
The varied types of modern deposit of the present-day Southern Bight are used as a partial guide for a review of the diachronous deposits of the Holocene marine transgression. The flooding of the barrier separating the Southern Bight from the North
Standort-und Nutzungsprobleme mineralischer Rohstofflagerstätten in Weltmasstab. (Location and utilization problems of mineral raw material deposits in a global scale)
An essential supposition for the effective utilization of deposits is their geologic-ecological valuation. Four groups of deposits with different value, quantity and quality are distinguished. The territorial effects of the historical location
development of exploitable deposits are characterized in a global scale. With consideration of actual problems special attention is drawn to the transport facilities. Finally various means to a higher technic-economical availability of mineral raw materials
are shown, especially by complex utilization of the existing deposits. (HL).
Recognizing terrigenous depositional environments with the aid of the computer in Geomathematical and petrophysical studies in Sedimentology. An international Symposium.
A FORTRAN program designed to simplify and duplicate the mental processes which lead to an interpretation of a depositional setting is presented. In order to simplify the geologic interpretation of clastic depositional environments, seven general
characteristics can be recognized. By defining which features are exclusive of a specific depositional setling a simplified basis for environmental interpretation can be established. Given a list of such features, a series of depositional environment eliminations
Der rezente ozeanische Ablagerungsbereich-Topographie, Sedimente, Stoffbestand. (The recent oceanic depositional environment. Topography, sediments, composition of materials)
The A. gives a review of oceanic areas of the world, which obtain increasing importance concerning in the development of geological sciences with regard to the basic geological research as well as to the applied geological research, especially
Geormorphological and geological history of the middle part of the Blue Nile Basin (Sudan)
Newly acquired data from the Blue Nile Valley in the Sudan indicate that the early sediments of the river system were deposited in structurally controlled basins during Tertiary and Quaternary times. Deposition is related to glacial and periglacial
activity in the Ethiopian Plateau. The sediments which represent braided channel deposits were derived from local basement complex rocks and volcanic rocks of the Ethiopian Plateau.
Zusammenhänge zwischen geologischem Untergrund und Flozbildung am Beispiel der Braunkohlenlagerstätte Wallendorf. (Connections between geologic underground and formation of seams at the exemple of the Wallendorf brown-coal deposit)
results of the main prospection work led to essential conclusions on the interrelations between the geologic underground formation of seams and coal qualities. Thus it became possible to find out possible areas of brine-breakthrough, to explain deposit
Clustered streamlined forms in Athabasca Valles, Mars : evidence for sediment deposition during floodwater ponding
A unique clustering of layered streamlined forms in Athabasca Valles is hypothesized to reflect a significant hydraulic event. The forms, interpreted as sedimentary, are attributed to extensive sediment deposition during ponding
and then streamlining of this sediment behind flow obstacles during ponded water outflow. These streamlined forms are analogous to those found in depositional basins and other loci of ponding in terrestrial catastrophic flood landscapes. Likewise, the streamlined forms
in Athabasca Valley may provide the best opportunity to reconstruct the recent geologic history of the young Martian outflow channel.
The hot spring deposits near Magyarkút and their paleobotanical analysis (Börzsöny Mountains, Hungary)
The clarification of the location and origin of the siliceous-calcareous deposits north of Magyarkút (N-Hungary) can lead noteworthy conclusions in connection with the geological evolution in the environment of Szokolya Basin. According
calcareous spring deposits embedded into the diatomaceous environment, in the side of the Szalamandrás Hill rocks of presumably terrestrial origin were also recognised and described based on the flora present in them. Completing the former knowledge
, the study can claim, that among the hot spring deposits of Magyarkút, the terrestrial deposits of Szalamandrás Hill can definitely be separated from the rock complex of limnic origin - the latter being similar to the spring deposits of the Szokolya Basin
Some geological implications of average Quaternary glacial conditions
Geomorphic processes operating under average Quaternary conditions contributed importantly to landscape evolution. Examples of landscapes that may represent such average conditions include cirques and fluvial deposits of the Pacific Northwest
Einige neue Erkenntnisse zum geologischen Bau und zur Lagerstättenbildung im Erzgebirge. (Some recent findings on geological structure and on formation of deposits in the Ore mountains)
Quaternary deposits and geomorphological evolution of the Telesina Valley (Southern Apennines)
In the paper the A. outlines the results of a geologic and geomorphologic survey carried out in a sector of the Calore River basin (Telesina Valley), located in the Benevento Province (Southern Appenines, Italy). The data analysis conducted allowed
Radiocarbon ages and environments of deposition of the Wono and Trego hot springs tephra layers in the Pyramid Lake subbasin, Nevada
This paper presents new information on the age and environment of deposition of the Trego Hot Springs (THS) and Wono layers that indicate the surface of Pyramid Lake lay well below the Sqaw Creek site when the Trego tephra layer was deposited
. The studies indicate that the surface elevation of Pyramid Lake was at or below its spill point to Winnemucca Lake subbasin (1177 m) when the THS layer was deposited and was at its spill point to the Smoke Creek-Black Rock Desert subbasin (1207 m) when
