This roadside geology book is one of the latest in a series of similar books written for most, but not all (e.g. Kentucky), states in the Union. This book is similar in format to its predecessors; technically accurate while still able to be understood by the layman. What separates this edition from others is the use of color illustrations Reviews:

Back in time in the Sør Rondane Mountains, Antarctica. Today, Sør Rondane Mountains in the Queen Maud Land acts as a barrier to the Eastern Antarctic Ice Sheet in Antarctica. This is displayed by the difference in altitude of the ice surface to the south and north of the mountain chain.

To the south, ice surface reaches altitudes above meters above sea level and forms an. This authoritative volume is designed to bridge the gap between Antarctic geological researchers and other geological communities.

The text describes all major rock units found in Antarctica, and reviews Antarctic palaeontology, geophysics, petroleum prospects, and mineral resources. Antarctic geology; proceedings. [Raymond J Adie; International Council of Scientific Unions.

--The geomorphology and glacial geology of the Sør-Rondane mountains, Dronning Maud Land / T. Van Autenboer --Glacier fluctuations recorded by patterned ground, Book. New U-Pb zircon ages for the younger phase of magmatism in the Sør Rondane Mountains (East Antarctica) are combined with published igneous and metamorphic zircon ages and show evidence for.

The Sør Rondane Mountains of eastern Dronning Maud Land, East Antarctica can be subdivided into two different crustal terranes: the NE-terrane and the SW-terrane. The former is underlain by basement rocks of amphibolite-facies (unit A) and granulite-facies (unit B), and the latter by granulite-facies (unit C) to greenschist-facies (units D and D′) by:   2.

Overview of geology of the Sør-Rondane and metamorphism of the Sør Rondane Mountains. The Sør Rondane Mountains are underlain by low- to high-grade metamorphic rocks and various syn-metamorphic intrusive rocks of Neoproterozoic to Early Cambrian age (Fig.

1b). These rocks are cut obliquely by younger granitoid intrusions and various types of later unmetamorphosed felsic, mafic. Abstract. Structural investigations in western Sør Rondane, eastern Dronning Maud Land (DML), provide new insights into the tectonic evolution of East Antarctica.

One of the main structural features is the approximately km long and several hundred meters wide WSW‐ENE trending Main Shear Zone (MSZ). It is characterized by dextral high‐strain ductile deformation under peak amphibolite‐facies conditions.

Antarctica, the last of the continents to be explored, has long been recognized as a critical piece of the world's geology.

The geology of West Antarctica has much in common with the geology of the Andes. In fact, this side of Antarctica owes its origin to the same mountain building processes that uplifted the western side of South America.

During the early Jurassic (around myr ago) oceanic crust began to subduct beneath the Pacific margin of Gondwana. The Antarctic and Its Geology by A. Ford and D. Schmidt To the seamen of the 18th century who skirted its ice-choked seas in their wooden vessels, Antarctica was known as "Terra Australis lncognito"-the unknown land of the south.

The Sør Rondane Mountains (22°°E, 71°40′°20′S), Dronning Maud Land, East Antarctica are situated within a collision zone related to the formation of the Gondwana supercontinent.

A metapelite preserving prograde and retrograde zoning in garnet from Mefjell, southern Sør Rondane Mountains (SRM), East Antarctica is described in detail and U–Th–Pb geochronological data are. Volcanic ash particles were extracted from tephra-bearing ice samples collected from Nansen Ice Field south of the Sør Rondane Mountains, Antarctica.

Particles are fresh glassy volcanic ash with diameters of ~50 μm, and chemical composition of the matrix glass belongs to a low-K basaltic andesite group, ranging from SiO2 60–62 wt% and K2O – wt%.

In an ice-free mountain area of the Sør Rondane Mountains, East Antarctica, Matsuoka () highlighted that long-term exposure to the cold desert climate has led to differential weathering and contrasting landscape by lithology: one end member is rootless, mushroom-like boulders with reddish rock coating resting on fractured bedrock (e.g., granite), and the other is pebble-size.

Field observations of weathering processes and the related landforms, combined with laboratory analyses of weathering products, permit a synthetic evaluation of Late Cenozoic weathering environments in the Sør Rondane Mountains, Antarctica, an arid upland characterized by.

In situ analysis of a garnet porphyroblast from a granulite facies gneiss from Sør Rondane Mountains, East Antarctica, reveals discontinuous step‐wise zoning in phosphorus and large δ 18 O variations from the phosphorus‐rich core to the phosphorus‐poor rim. The gradually decreasing profile of oxygen isotope from the core (δ 18 O = ~15‰) to the rim (δ 18 O = ~11‰) suggests that.

The Sør Rondane Mountains are underlain by Late Proterozoic metamorphic rocks of the Teltet-Vengen Group and the Nils Larsen Group gneisses, which are intruded by latest Proterozoic to Early Paleozoic plutonic rocks and dykes.

Geological Evolution of Antarctica is a collection of papers presented at the Fifth International Symposium on Antarctic Earth Sciences, held under the auspices of the Scientific Committee on Antarctic Research (SCAR) at Robinson College, Cambridge, August Reviews: 1.The summar party of the 27th Japanese Antarctic Research Expedition (JARE) () performed the geological survey in the central part of the Sør Rondane Mountains, East Antarctica.

The area is underlain by various kinds of metamorphic and plutonic rocks, of which the metamorphic rocks are tentatively divided by lithology and geologic.The Sør Rondane Mountains (22°E°E) are located in eastern Dronning Maud Land, East Antarctica, and consist of amphibolite to granulite facies metamorphic rocks and various intrusive rocks.
