In describing the general physical features of the country, the most significant point to notice is that (though it falls westward to the sea and rises eastward to an elevated plain) the rise from west to east is not continuous, but is sharply interrupted by the deep fissure of the Ghor or Jordan valley; which, running from north to south - for the greater part of its length depressed below sea-level - forms a division in the country of both physical and political importance.
In Abyssinia the Ashangi traps are certainly post-Oolitic. In East Africa the fissure eruptions are considered to belong to the Cretaceous.
Copper, lead and zinc are produced in small quantities, being found in fissure veins with gold and silver.
The copper is mostly a copper glance passing into chalcopyrite; it is found in fissure veins with granite.
The earlier supposition that these vast lava flows came chiefly from fissure eruptions has been made doubtful by the later discovery of flat-sloping volcanic cones from which much lava seems to have been poured out in a very liquid state.
A fissure was formed extending nearly 9 m.
The Spigelian lobe is represented by a flat surface between the postal fissure and the posterior border, not distinctly marked off from the left lateral by a fissure of the ductus venosus, as this vessel is buried deep in the hepatic substance, but the caudate lobe is distinct and tongue-shaped, its free apex reaching nearly to the border of the right lateral lobe.
The anther consists of lobes containing the minute powdery pollen grains, which, when mature, are discharged by a fissure or opening of some sort.
Nor was the fissure in the Protestant ranks closed, and Charles took advantage of this disunion to conquer Gelderland and to mature his preparations for overthrowing the league of Schmalkalden.
The ores are almost exclusively gold, tellurides being the most characteristic form, and occur in fissure veins.
