A new lithostratigraphical unit, the Navarana Fjord Member of latest Llandovery age, is formally erected in this paper. It consists of an up to 80 m thick sequence of amalgamated carbonate conglomerate beds. The member is presently known from the east and west coast of Navarana Fjord, central North Greenland. It rests or, Silurian carbonate platform to the south. To the north of the platform margin scarp it rests on and interfingers with turbidites of the Merqujôq Formation. The member is inc!uded in the Merquj6q Formation and forms an important marker reflecting the final foundering of the outer carbonate platform.

Limestone outcrops of the Tacipi area is an ideal carbonate platform part of Neogene East and West Sengkang Basin that are located in the south part of Sulawesi, precisely in western of Bone city. The limestones of this area, outcropping mainly on the north-south oriented hills such as Temapole, Anadara, Tamping, Lappa, etc., are the best reef example in the Tacipi area, as the reef itself, its debris and detritus can be distinguished in the field. Throughout the ridges and pinnacle in Tacipi field the limestones are predominantly homogenous boundstones on the top and detrital bioclastic packstones with local grainstones, and wackestones at the bottom. There are four major reef zonation indentified pacth reef, barrier reef, fore reef and lagoon. The extensive freshwater leaching of fossil fragments and calcareous cement give the preservation of biomouldic and vug pore spaces.

Batugamping di daerah tersebut, terutama tersingkap berorientasi utara – selatan sejajar gunung-gunung seperti di Tempole, Anadara, Tamping, Lappa dan lain-lain, merupakan contoh terumbu terbesar di daerah Tacipi, sebagai bagian dari terumbu, sisa-sisa dan runtuhannya dapat dibedakan di daerah tersebut. Sepanjang punggungan dan puncaknya di daerah Tacipi, batugamping merupakan bagian utama dari lapisan pengikat yang homogen di bagian atas dan detrital bioklastik koral terpilah buruk dengan lokal struktur butiran secara setempat, dan struktur bioklastik laut pada bagian bawah. Ada empat zonasi utama terumbu yang telah identifikasi sebagai karang gosong, karang penghalang, karang depan dan lagun.

Land Region

The Peary Land region in North Greenland (fig. 31) contains a sequence of Lower Palaeozoic sediments which is probably more than 4 km thick (Dawes, 1976; Christie & Peel, 1977; Hurst, 1979; Christie & Ineson, 1979; Hurst & Surlyk, 1980; Ineson & Peel, 1980; Surlyk, Hurst & Bjerreskov, 1980). From Early Cambrian to Wenlock the area was divided into a northern turbidite trough and a southern, mainly carbonate platform (fig. 32). The platform seems to have undergone several phases of backstepping to the south, accompanied by expansion of the turbidite basin (fig. 32) (Surlyk et al., 1980). The region was affected by an orogeny of assumed Devonian - early Carboniferous age (Dawes, 1976). Deformation is most intense in northern Johannes V. Jensen Land (fig. 31), where an amphibolite facies is attained along the north eoast (Dawes & Soper, 1973) and decreases southwards, leaving the platform earbonates virtually undeformed. A separate, strongly block-faulted sedimentary basin, the Wandel Sea Basin is present in eastern Peary Land and farther to the south-east (Dawes & Soper, 1973; Håkansson, 1979). It eontains a sequenee of Upper Palaeozoie carbonates and Upper Palaeozoic - Mesozoic mainly coarse clastics more than 3 km thick.

This paper uses customs figures to show that herring exports from the east and west coast lowlands expanded significantly in the last six decades of the sixteenth century. The paper argues that the rise was primarily due to the north-west Highland fisheries being opened up and exploited by east and west coast burghs. These ventures required greater capital supplies and more complex organisation than their local inshore fisheries and they were often interrupted by political hostilities. However, the costs were a fraction of those required to establish a deepwater buss fleet, enabling Scotland to expand production and take advantage of European demand for fish while minimising additional capital costs.

In dealing with this subject it is essential to define the high rainfall districts, and on, perusing a rainfall map it was found, contrary to expectations, that the greater part of the North Island, as represented by the Auckland Province and Taranaki, has a rainfall of over 50 inches per annum. In the same category falls the West Coast of the South Island and all of Stewart Island.

A series of smal! volcanic centres cut Ordovician turbidites of Formation A in the southem part of Johannes V. Jensen Land between Midtkap and Frigg Fjord (Map 2). Their general location and main rock types were described by Soper et al. (1980) and their nomenclature is adopted here for fig. 22 with the addition of the small pipe B2. A further small intrusion, south-west of Frigg Fjord, was described by Pedersen (1980). The centres lie 5-10 km south of, and parallel to, the important Harder Fjord fault zone (fig. 22) which traverses the southern part of the North Greenland fold belt and shows substantial downthrow to the south (Higgins et al., this report).

The north-east 'corner' of Greenland is geologically probably the least known region in North Greenland. Various expeditions have visited the coastal parts but geological detail, particularly faunal information, has remained surprisingly scarce. Initial field work by Koch (1923, 1925) and Troelsen (1949a, b, 1950) showed that a Precambrian to Silurian section - unfolded in the south, folded in the north - was unconformably overlain by a Carboniferous to Tertiary section, now referred to as the Wandel Sea basin (Dawes & Soper, 1973).

Geochemical maps and geochemical cross-sections, based on chemical analyses of the < 0.1 mm fraction of stream sediment samples collected at a density of approximately 1 sample per 30 km2 in central and western North Greenland, show that the distribution patterns for the major elements and some trace elements reflect the main lithological units of the North Greenland Palaeozoic platform and trough. By contrast the distribution patterns for S and Sr are different. High S values are correlated with zones of tectonic activity and are thought to indicate migration of H2S along faults. High Sr values are correlated with evaporitic rocks in the platform sequence and with deep sea carbonates. High BaO values occurring along the Silurian platform margin and in the Ordovician platform-slope sequence are the result of Ba enrichment in the sedimentary environment, combined with epigenetic vein-type baryte mineralisation.

Geology.—Stated roughly, the geology of the Department of Finistère may be said to consist of two masses of granite, one to the north and one to the south, enclosing between them nearly the whole of the sedimentary rocks of the district. These consist of Cambrian slates and gneiss, Lower, Middle, and Upper Silurian slates and grits, and very small and unimportant patches of Upper Carboniferous shales. The entire mass of these deposits has an east and west direction, and occupies the central part of the Department.

In plan the walls surrounding the Acropolis of Sparta form an irregular oblong, terminated to the east and west by two small hills which formed citadels or outlook points. Though no single complete part remains, and in many places the walls are levelled to the ground, the lines can still be traced fairly completely. (Plate VIII. 3.)At the south eastern corner are the ruins of a Roman Stoa of the Imperial period (A). They shew a series of small compartments (Fig. 1), covered with barrel vaults, ten on either side of three larger central rooms, which are roofed with crossgroined vaults and large semicircular niches at the back. The ground on the north side is as high as the vaults and originally must have formed a terrace overlooking the street on to which the Stoa opened on its south side.
