The Grenvillian Orogeny was preceded by extensive anorogenic volcanism and plutonism in the period 1500–1300 Ma in the form of rhyolites, epizonal granites, anorthosites, gabbros, alkaline complexes, and basic dykes. An analogue for the mid-Proterozoic anorogenic complexes is provided by the 2000 km by 200 km belt of anorogenic complexes in the Hoggar, Niger, and Nigeria, which contain anorthosites, gabbros, and peralkaline granites and were generated in a Cambrian to Jurassic rift that farther south led to the formation of the South Atlantic. An analogue for the 1 × 106 km2 area of 1500–1350 Ma rhyolites (and associated epizonal granites) that underlie the mid-continental United States is provided by the 1.7 × 106 km2 area of Jurassic Tobifera rhyolites in Argentina, which were extruded on the stretched continental margin of South America immediately preceding the opening of the South Atlantic. The mid-Proterozoic complexes were intruded close to the continental margin of the Grenvillian ocean and were commonly superimposed by the craton-directed thrusts that characterized the final stages of the Grenvillian Orogeny. The bulk of the Keweenawan rift and associated anorogenic magmatism formed about 1100 Ma at the same time as the Ottawan Orogeny in Ontario, which probably resulted from the collision of the island arc of the Central Metasedimentary Belt attached to the continental block in the east with the continental block to the west. The most appropriate modern equivalent would be the Rhine Graben, which formed at the same time as the main Alpine compression.

The Scandinavian peoples emerge into the light of history much later than their neighbours in the South and the West, the Teutons on the Continent and in England. It was only through the Viking raids that the Nordic peoples came into touch with the rest of Europe, and were gradually converted to Christianity. Long after the introduction of the Christian faith they preserved many peculiar and archaic traits. Thus the Nordic peoples retained, with great tenacity and conservatism, their ancient judicial system. This system has therefore been the object of considerable interest even outside Scandinavia, although the manuscripts through which it has become known are much later than the corresponding documents of other Teutonic nations.An investigation of the localities where justice was dispensed in former ages is of importance not only for the history of civilization, but also as a complement to the study of oral and written tradition, and thus to the history of law itself. In view of the many points of similarity between the judicial systems of the various Teutonic nations, some notes on the Thing-steads, or places of assembly, in Sweden, Norway, and Denmark, may perhaps be of interest to English-speaking readers.

Chapters 2–6 survey the political and socioeconomic forces underlying the global sustainability crisis. Understanding the scale and depth of contemporary forces of capitalism and consumerism requires a close look at the consequences of imperialism and colonialism on patterns of violence and exploitation. This chapter begins this process of understanding by sketching the history of ecological imperialism after 1600, seeing this as a reasonable starting date for the beginning of what many scholars are now calling the Anthropocene Epoch (or the age of humans, replacing the geologic epoch of the Holocene beginning 12,000 years ago). It opens with Captain Pedro Fernandes de Queirós’s voyage across the Pacific Ocean in 1605–06 to “discover” modern-day Vanuatu, before turning to look more globally at the devastation of imperialism – and later colonialism – for the South Pacific, the Americas, Africa, and Asia. Over this time conquerors enslaved and murdered large numbers of indigenous people; cataclysmic change came as well, however, from the introduction of European diseases, plants, and animals. This chapter’s survey of imperialism, colonialism, and globalization sets the stage for Chapter 3, which explores the devastating history of the South Pacific island of Nauru after 1798.

The Appalachian Orogen is divided into five broad zones based on stratigraphic and structural contrasts between Cambrian–Ordovician and older rocks. From west to east, these are the Humber, Dunnage, Gander, Avalon, and Meguma Zones.The westerly three zones fit present models for the development of the orogen through the generation and destruction of a late Precambrian – Early Paleozoic Iapetus Ocean. Thus, the Humber Zone records the development and destruction on an Atlantic-type continental margin, i.e., the ancient continental margin of Eastern North America that lay to the west of Iapetus; the Dunnage Zone represents vestiges of Iapetus with island arc sequences and mélanges built upon oceanic crust; and the Gander Zone records the development and destruction of a continental margin, at least in places of Andean type, that lay to the east of Iapetus.The Precambrian development of the Avalon Zone relates either to rifting and the initiation of Iapetus or to subduction and a cycle that preceded the opening of Iapetus. During the Cambrian Period, the Avalon Zone was a stable platform or marine shelf.Cambrian–Ordovician rocks of the Meguma Zone represent either a remnant of the continental embankment of ancient Northwest Africa or the marine fill of a graben developed within the Avalon Zone.Silurian and younger rocks of the Appalachian Orogen are mixed marine and terrestrial deposits that are unrelated to the earlier Paleozoic zonation of the system. Silurian and later development of the orogen is viewed as the history of deposition and deformation in successor basins that formed across the already destroyed margins and oceanic tract of Iapetus.

AbstractThe article outlines the Mongolian influences on the biggest horse race festival in Nagchu prefecture in the Tibetan Autonomous Region (TAR).Since old times these horse races have been closely linked to the worship of the local mountain deity by the patrilineal nomadic clans of the South-Eastern Changthang, the North Tibetan plain. In the seventeenth century the West Mongol chieftain Güüshi Khan shaped the history of Tibet. To support his political claims, he enlarged the horse race festival's size and scale, and had his troops compete in the different horse race and archery competitions in Nagchu. Since then, the winners of the big race are celebrated side by side with the political achievements and claims of the central government in power.

AbstractThis article offers the first study of the Cahiers d’Histoire Mondiale, the Journal of World History published under the auspices of UNESCO from 1953 to 1972 as a by-product of the ‘History of mankind’ project. Drawing on material in the UNESCO archives, it delves into what Lucien Febvre, the first editor of the Cahiers, called his ‘kitchen’, in order to understand world history as a practice. Data on author origin and article subject matter point to the journal’s mitigated success in overcoming Eurocentrism. The article ultimately contends that the Cahiers was at once a laboratory that experimented with new forms of relational history, and a forum where the very nature of world history was discussed by scholars from around the world (mainly from the West, but also from the East and the South). It suggests that today’s epistemological discussion on global history might benefit from the reflection offered by this now largely forgotten experiment.
