Jan 01, 2009· Manganese contents in Lahn–Dill-type Fe deposits may increase to such an extent so as to form a separate entity of a Mn SEDEX ore, as near Battenberg in Hessen, Germany (Schaeffer 1998). Anomalously high Mn contents are known as proximity indicators of the feeder channels of stratabound base metal and iron deposits ( Stumpfl, 1979 ).
The closest analogues, according to the author, are the well-known iron ore deposits of the Lahn-Dill region in Germany, which made it possible to propose an alternative …
Exogenic deposits include deposits of bog iron ores and some of the siderites and silicate rocks (in the USSR, the Kerch' deposit in the Crimea and the Aiat deposit in the Kazakh SSR; and Lahn-Dill in the Federal Republic of Germany).
2.78% of all Copper deposits have Iron. 4.30% of all Iron deposits have Copper. Silver: 179: 11,469: 1.56% of all Silver deposits have Iron. 2.53% of all Iron deposits have Silver.

In such basins, many deposits linked with the volcanic thermal energy were formed: SEDEX deposits of the Meggen-type, iron deposits of the Lahn-Dill-type and VMS base metal deposits, the latter being the only ones known in the FMC (Brévenne deposits).
The Lahn-Dill type deposit of Malý Děd located in the Silesian domain is a part of the Devonian metasedimentary and metavolcanic cover rocks (Vrbno Group) that contain about 30 small Lahn-Dill type iron-ore occurrences. The Malý Děd deposit occurs in close association with muscovite-biotite gneiss of the Precambrian Desná Dome.
Mar 01, 2010· Such pillow fragment breccias generally make up the bulk of the so-called "Schalstein" of the Lahn-Dill area. A hematitic iron ore deposit is developed on top of the volcanic succession and occurs in the east wall of the quarry where it is cut by several small thrusts. Massive coarse debris flow deposits continue the profile to the top and ...
The stratiform iron ore deposits of the Lahn-Dill type, which were economically important until the 1970s, are associated with these volcanoes and are genetically related to diagenetic interaction ...
Middle Devonian series hosting the base metal deposits—SHMS, VHMS and Lahn-Dill-type (Fe oxides) deposits (consult references for lithological details). From west to east: Iberian Pyrite Belt (after Tornos 2006); Rhenish deposits, Harz domain and Moravo-Silesia (Izera) deposits (after Large 2003b). Two main events can be dis-

Thus, Otlukilise iron deposits represent an other sample of Lahn-Dill type syn-sedimentary volcanogenic or exhalative-sedimentary type ore for-mation as Deveci Iron Deposits (Hekimhan-Malatya, Turkey) do.
Ore deposits could be determined down to a depth of 900 m. 1866, after the annexation of the Duchy of Nassau by Prussia the mine was managed by the Prussian mountain inspection Dillenburg. In 1890 the old main shaft was sunk. In 1937 Buderus took over the Königszug mine. When war broke out in 1939, around 12,000 tons of ore were mined each month.
