TL;DR: In this paper, the concept of Adria as having behaved as a promontory of the African plate is tested by correlation of the main tectonic events in the belt with the spreading history of the Atlantic.

TL;DR: A recent review of marine-based investigations reveals a lack of generally accepted criteria for the recognition of contourites on the basis of sediment character as discussed by the authors, and the problems in establishing such criteria and recognize that a continuum may exist between dilute turbidity flows, bottom currents and hemipelagic settling.

TL;DR: In this article, the authors compare the geochemical characteristics of high-level and deep-level tonalites and trondhjemites, and show that the latter is a more basic field than the former.

TL;DR: The most recent drumlin origin theories are examined in the light of our knowledge of the subglacial environment as mentioned in this paper and the interdisciplinary nature of present research into drumlins is stressed.

TL;DR: In this paper, 15 non-palinspastic palaeotectonic maps of Australia and New Guinea are presented to illustrate the progressive development of the Australian continental block from the Archaean to the present.

TL;DR: In this paper, a review of the literature indicates that several factors must be considered in any investigation of ice action in the lacustrine environment in the James Bay area, subarctic Quebec.

TL;DR: Tectonic slides are faults that have been described and discussed in the Caledonides for over fifty years but which, possibly because of misunderstanding, have failed to find acceptance in structural schemes elsewhere.

TL;DR: A review of the literature shows that only a few cores have been systematically analyzed for 230 Th and/or 231 Pa; and despite a proliferation of microfossil and stable isotopic studies, no systematic XRD investigations have been attempted in this decade (except for indirect methods such as gamma ray or alpha track analyses, which measure neither uranium nor protactinum directly).

TL;DR: In this article, the reader is introduced to the highly complex matter of colloid chemistry and its role in geochemistry, pedology, oceanography, and geology, as well as its role as a real synthesizer.
