Laboratory Manual in Physical Geology is the most widely adopted, user-friendly manual available for teaching laboratories in introductory geology and geoscience. The manual has been produced under the auspices of the American Geological Institute (AGI) and the National Association of Geoscience Teachers (NAGT). It is backed up by an Internet site, GeoTools (ruler, protractor, UTM grids, sediment grain-size scale, etc.), Instructor Resource Guide, Instructor Slide Set, Instructor Transparency Set, and a Digital Image Gallery (DIGIT) CD-ROM.'

The average introductory geology student’s perception of geology normally involves the memorization of rocks and discussions of  natural disasters, but Geology contains so much more. Geology is the study of our planet, which is vital to our everyday lives from the energy we use, to the growing of the food we eat, to the foundations of the buildings we live in, to the materials that are used to make everyday objects (metals and plastics). The ideal place to start this course is discussing the methods that are used to better understand our planet, the processes that shape it, and its history.

К лампрофирам, после открытия Гумбелем (1874), в течение целого столетия относились как к непонятным редкостям. Несмотря на то, что эта ситуация, с ростом количества публикаций и активности работающих в этом направлении, в последнее время изменилась, лампрофиры остаются едва ли не единственной группой изверженных пород, которой еще не посвящена отдельная монография.

Africa is a huge continent covering 30-3 million km2 or about twenty per cent of the earth’s land surface. The continent extends some 8000 km through 72 degrees of latitude from Cape Agulhas in the south (34 51'S) to Cape Blanc in the north (37° 51'N) and its greatest east-west length lies between Ras Hafun (51° 50'E) and Cape Verde (17° 32'W), a distance of 7200 km. Africa has over three-quarters of its area lying within the tropics and one third is affected by wind belts producing arid and semi-arid conditions. <...>
