ABSTRACT: Although tin minerals have been determined in Anatolia, any tin deposit, economicaly feasible, hasnot been explored yet However, tin was. used as. an alloy material five thousand years ago in the country of the civiliza- " tions, Anatolia,. Existance of tin deposit which was exploited in the period of Before Christ in Anatolia, has been explored by geo-archaeological researches in recent years,. The: mentioned old tin mine is in the village of Celaller area. (Niğde). Existance of cassiterite`mineral in that area was explored, in. 1986. The origin of the word cassiterite is old Greek language and it was derivated from, "kassiteros". The word kassiteros has still being used in the meaning of tin in Greek language. ,_. Research works that is oriented to find out the existance` of tin in Anatolia has. started from second half of the nineteenth century and covered. 124 years till now,.. Cassiterite: mineral.izati.oo. which has certainly been, located in Celaller» Turkey,, points out that new tin. exploration studies should be carried out in this region, in order to findnew deposits.
ABSTRACT : In terms of natural resources the Turkish states that become newly independent central Asia have- great. potentialities.
ABSTRACT: Two kinds of methods of alpha track, measurement were carried, out for earthquake and active faults along `the North Anatolian Fault One of them is the short term, other is the continuous measurement method for evaluating the faulty activity.The results by the short, term, method show that, .alpha, track, measurement, is useful to detect even in. the regions repioducibilitiy of the alpha track, measurement if measured, in. nearly the same- temperature condition.The results by the continuous measurement, method show mainly. In both two methods, however, the undergrond water supply must be taken into consideration before evalution.In. Mekece region, east of Iznik, the seismic gap area of one branch of the North Analolioo Fault Zone» the maximum .alpha track, density obtained, by both methods is abnormally high,.. Furthermore, the result, by the long term measuring method shows, the highest value in winter,., These facts indicate that this, branch of the- North Anatolian. Faults, is. very active
ABSTRACT: The studies area covering near Kelkit (Gümüşhane) region, is located in. Fontid tectonic unit and in its south zone. In this study beeing based on litfaosteatigraphy laws, seven units have been identified in the formation rank. Gümüşhane granite forms the basement of study .area.., Lias aged. Zimonköy formation forming the first marine rocks consist of sedimantary-volcanic character .and represents lateral, .and horizontal fades changes, Berdiga formation, all of which is developped in carbonaceous faciès» composed of mainly sandy limestone, dolomitic limestone and dolomites. Upper cretaceous aged. Kermuidere formation is représentée by conglomerates, derived mainly Berdiga formation. Paleocene aged Ziyarettepe formation is framed-by red sandy limestone developped in. open marine environment.., Alibaba formation is developped in three different faciès that are laterally interfingerig at Middle Eocene- Lower Miocene time,.. Smırgöltt limestone: which is recognized by horizontal limestone is deposited in restricted environment
