Urban geoscientific data of East and Southeast Asia: GIS data sets of 11 cities This CD-ROM set is the final product of the DCGM III Project. It is a feasibility study of the application of geological data for preliminary urban planning. consists of autochthonous assemblages of 2, to 2,million-year-old metavolcanic rocks and their intrusive equivalents, which are unconformably or disconformably overlain by the Ma Porcupine and 2, to 2,million-year-old Timiskaming metasedimentary assemblages .
A CD-ROM of datasets and computer coding using programs such as WinBUGS and S-PLUS accompanies the book. Catalog no. , ISBN: March , 7 x 10, pp. Suggested Price: $ The Independence Creek (“Boulevard”) area in the Dawson Range district in west-central Yukon has recently received new government geological mapping; however, little is known about the nature or origin of gold mineralization in this region. A regional metallogenic framework for the mineralization is proposed herein, based on geological, structural, geochronological, and fluid inclusion.

2. Tectonic and geophysical background. The Canadian Shield, the Precambrian core of North America, is an assemblage of tectonic provinces with very different ages and histories (Hoffman, ).One of these provinces is the Proterozoic Grenville Province, forming a belt ≈ – km wide along the southeastern margin of the Canadian Shield (Fig.
1, inset).Cited by: 2. Based on geochronological information, six volcanic assemblages are distinguished that formed by submarine volcanic activity between ca.
and Ma. These assemblages are referred to, from oldest to youngest, as the Pacaud, Deloro, Stoughton-Roquemaure, Kidd-Munro, Tisdale, and Blake River assemblages. The polyphase evolution of the Seridó Belt (NE-Brazil) includes D 1 crust formation at – Ga, D 2 thrust tectonics at Ga and crustal reworking by D 3 strike-slip shear zones at Ma.
Microstructural investigations within mylonites associated with D 2 and D 3 events were used to constrain the tectono-thermal evolution of the belt.
D 2 shear zones commenced at deeper crustal levels Cited by: Uncertainty into the nature and presence of pre-plate tectonic regimes and the timing of any change in tectonic regimes relates to the incompleteness of the rock archive in deep time, differences in the criteria used to infer the existence of plate tectonic and pre-plate tectonic regimes on the early Earth (ca greater than Ga), and Cited by: Tectonic map of North America, showing location of the Archean Superior Province at the core of the Canadian Shield (after Hoffman, ).

A set of sheeted quartz veins cutting Ma monzogranite at Sandwich Point, Nova Scotia, Canada, provide an opportunity to address issues regarding fluid reservoirs and genesis of intrusion-related gold deposits.
The quartz veins, locally with arsenopyrite (≤5%) and elevated Au–(Bi–Sb–Cu–Zn), occur within the reduced South Mountain Batholith, which also has other zones of anomalous. texts All Books All Texts latest This Just In Smithsonian Libraries FEDLINK (US) Genealogy Lincoln Collection.

During Jurassic and Early Cretaceous time, arc magmatism in the Klamath Mountains province was episodically punctuated by contractional deformation (Wright and Fahan, ; Hacker and Ernst, ; Hacker et al., ).These contractional events are represented by regional thrust faults that separate distinct, commonly arc-related, tectonostratigraphic terranes (Irwin,Access: CD-ROM  or CD-ROM  Description: The Tectonic Geology Data Set is a digital interpretation of the Tectonic Geology of the Province of Ontario, It illustrates this by 1) grouping volcanic and sedimentary rock units into tectonic assemblages in Precambrain terrains and depositional sequences in the overlying Paleozoic and.
The assemblages define a metamorphic field gradient (see Chap. 3) and rocks on this P–T-array are said to be of low grade at low P–T and of successively higher grade with higher P–T conditions.
The term metamorphic grade is a qualitative indicator of the physical conditions that have been operating on the rocks. 11 ORBITAL FORCING Introduction The nature of Milankovitch processes Components of orbital forcing Basic climatology Variations with time in orbital periodicities Isostasy and geoid changes Nonglacial Milankovitch cyclicity The nature of the cyclostratigraphic data base The geologic.

For the Second Edition of Earth Structure: An Introduction to Structural Geology and Tectonics, the authors have heavily revised each chapter while preserving the overall structure of the First Second Edition also benefits from new artwork that clearly illustrates complex concepts.

Blue letters below the trace denote the time interval between arrivals, which is either the two‐way P travel time (2P) or the time difference between an S and a P leg in the soft layer.
2. Geologic framework. In common with other Early Archaean rocks of the outer Godthåbsfjord region (figure 1), two main lithologic assemblages comprise rocks on Akilia and most abundant is approximately – Gyr composite, banded, tonalitic gneisses (Nutman et al.; Whitehouse et al.
), historically referred to as the Amîtsoq gneisses. Abstract U/Pb zircon/titanite geochronology, in situ monazite geochronology, and 40Ar/39Ar thermochronology provide an unusually complete data set for reconstructing the tectonic history of Proterozoic rocks exposed in the Black Canyon, Gunnison, Colorado.
These new geochronologic data record three protracted orogenic episodes and an exhumation event between orogenic pulses: (1). The compositional Se has been quantitatively determined with TCF-INAA in the NIST variability increases still further in the mineralized assemblages of Stage III, in series of glass and a set of selenium-doped NiS beads have been produced with which sulphides exhibit the range + to +, chalcopyrite generally selenium concentration.Furthermore, the digitised geological maps (on the attached CD-ROM) are correlated and harmonised according to the current stratigraphic time table.
