  • Carpathian Mountains ; Mountain ; Romania ; Structural geomorphology
  • The Căpăţinii Mountains lie in the middle region of the Southern Carpathians in Rumania. Their rocks are very varied in type. From the geographical point of view the mountain can be divided into four parts (according to the A.). The biggest part
  • of the mountains are the main ridge. The E-SE part is called Muntii Olăneştilor, it is made up mainly of detritic sedimentary rocks. The most interesting part is the massif called Buila-Vînturariţa. It is made of Jurassic limestone. Piatra Tîrnovului on the NE edge
  • of the mountains is also made up of Jurassic limestone. It is much smaller in area than Buila-Vînturariţa Massif. - (ZK)

  • Asia ; Geomorphology ; Himalaya ; India ; Mass movement ; Moraine ; Mountain ; Pakistan ; Permafrost ; Rock glacier ; Sediment transport
  • This paper will examine the characteristics and distribution of rock glaciers in the Karakoram Mountains and northern India to highlight importance as geomorphological agents and to assess geomorphological significance.

  • Some observations regarding mountain permafrost in the Japanese Alps
  • Geophysics ; Japan ; Mountain ; Periglacial features ; Permafrost ; Rock glacier
  • In the early 1970s permafrost was discovered from 2 Japanese volcanoes, Mt. Fuji and Mt. Daisetu, by means of shallow drilling and geophysical sounding. The last 2 decades have encountered a rapid progress in mountain permafrost researches. The most

  • Geomorphogenesis ; Hungary ; Mountain ; Periglacial features ; Volcanism
  • The range of Tokaj Mountains is not only different from the rest of our volcanic mountains because of its N-S direction, but also the duration and extent of its volcanism, its volcanic material ; and the paleogeographical circumstances were
  • different too. As a result of all this, the mountain is very rich in morphological forms. In Hungary, these mountains are the richest in periglacial forms thanks to the varied collection of rocks and their settlement characteristics. - (ZK)

  • Forest diversity, distribution, and dynamique in the Itombwe Mountains, South-Kivu, Congo Democratic Republic
  • Biodiversity ; Deforestation ; Environmental conservation ; Forest ; Human impact ; Mountain
  • Paper begins with a detailed description of the Itombwe Mountains forest, near Lake Tanganyika, in the congo (formely Zaire), based on bibliographic review, landscape traverses in 1992-1993, and remote sensing data from 1980-1985. Author considers
  • these mountains to be the second most important, if not the most important, location of highland forests in continental Africa, with a very high level of biodiversity, wide range of vegetation types, and a wide range of forest types. Their conservation

  • Hungary ; Landscape ; Mountain ; Region
  • The North Hungarian Mountains stand third among the macroregions of Hungary with an area of 11,500 square km, extending between the Great Hungarian Plain and the northern state border (with Slovakia). From landscape geographical viewpoint
  • the macroregion can be subdivided to seven mesoregions ; in each of the latter there is a core with a mountain group. - (ZK)

  • Hungary ; Mountain ; Structural geomorphology ; Volcanism
  • The Tokaj Mountains differ from the other volcanic mountains of Hungary by strike, heavy dissection, (a younger) age of volcanism, a great diversity of volcanic rocks, paleogeographic circumstances (frequent marine transgressions). The paper deals

  • Freeze-thaw cycle ; High mountain ; Mass movement ; Monsoon ; Mountain ; Nepal ; Periglacial features ; Rock glacier
  • The principal objective of this paper is the determination of geomorphic work accomplished by rockglaciers in the Khumbu Himalaya, and to compare this work with rates obtained in continental mountain ranges of the mid-latitudes.

  • Erosion and sediment yield in relation to afforestation and fire in the mountains of the Western Cape Province, South Africa
  • Afforestation ; Cape Province ; Fire ; Human impact ; Mountain ; Natural resources ; Sediment budget ; Soil conservation ; Soil erosion ; South Africa
  • The mountains of the Western Cape Province fulfil a vital water supply function. In order to protect the supply, it is important to understand the natural soil erosion rates in the mountains and human influence upon them. The variety of management

  • Gaddi Shepherds have had horizontal and vertical access to pastoral resources in the mountain commons for many years. During this time, they have maintained relationships with cultivators in the valleys and plains that sustained an ecological
  • balance in both the mountains and lowlands. Since the nineteenth century, changes in the political economy of the plains and an erosion of customary institutions in the mountains have threatened the precarious livelihood of the Gaddis. - (SLD)
