CONTENTS A I m ă ș a n B. : Towards new successes in mining in­dustry. Revista Minelor nr. 1/1959, p. 3—5. Bogdan G h. : New contributions to the study of the methan emanations in coal mines. The authors make a thorough analysis of methan .diffusion zones in gas bearing rocks surrounding the coal mines, creating possibilities to determine graphiaclly and analytically these zones. Revista Minelor nr. 1/1059, p. 6—18. Bonea I.: Another computing method in mining poly­­gonometry. The author is suggesting a calculating method for underground polygon surveying, by using the method of coordinates transformation. This me­thod offers several advantages enumerated in the conclusions of this paper. Revista Minelor nr. 1/1959, p. 18—19. Secară Gh. : Advances in the construction of control apparatus of mine-air. The construction principles and operating manner are exposed of some appa­ratus for determining certain gases from the mine air composition, based on the properties of the infrared rays. It gives also informations concern­ing the equipment of fixed stations for mine air analysis and of certain places with automatically recording and long distance transmitting signals apparatuses. Revista Minelor nr. 1/1959, p. 20—26. Samoilă I. and Popa I.: Chatcographic survey on complex pyrite and copper ores from Leșul Ursului­­region. It briefly describes the geological aspect of the region giving also the results of mineraio­­gical survey on patterns obtained from the deposit. The microscopic investigation led to the identifica­tion of: pyrite, blende, chaicopyrite, galena, mis­­pickel, tetrahedrite, magnetite, marcasite. chaicozine, covellite, bornite, gold, bismuthinite and molybde­nite as metal minerals, and chlorite, quartz, chal­­cite, muscovite, sericite and barytine as gangue minerals. Metal minerals are described according to the kinds of ore, with the parageneses and gra­nulometric classes characteristics. It concludes with considerations on genesis of deposit. Revista Minelor nr. 1/1959, p. 30—35. M a i e r u O. : Concerning the alteration process of the sepentine from Danube valley. It gives the following remarks on the alterated serpentines from Danube valley: a) The decomposition process of serpentine from the Danube valley is a unique phenomenon in Rumania. It is due to the excessive humidity of the region and covers a very limited area (8/10 km) ; b) From this decomposition we get many secondary minerals; c) The decomposed rock con­tains a great part of ,Ni hydroxide, soluble in or­ganic acid and diluted mineral acids. Garnierite is likely a geliform mixture of secondary minerals obtained from the decomposition process of serpen­tine in specific conditions. Revista Minelor nr. 1/1959, p. 35—37,
