Estimación de reservas de caliza en el sector Chuwitayo - Chiguaza

Abstract

The present graduation work called Assessment of limestone supplies at the area of Chuwitayo – Chiguaza located in Morona Santiago and Pastaza province; at Huamboya and Pastaza cantons; Chiguaza and Chuwitayo parishes; at the sector of Pastaza river, is a request of the inhabitants of the zone who aim to know the quality and quality of the supplies available, in orden to take better advantage of this non-metallic mineral. The recognition of the zone was performed; later on, the delimitation of the deposit in study, which is located inside the Napo formation, since this formation constains a big amount of fossilized limestone with a high percentage of calcium carbonate, here, the structural – geological survey was performed where 7 samples were collected in the most representative outcrops which were taken in the exposed slopes such as the slope displayed due to the construction of the Macas – Puyo road, in the slope of Chiguaza river, in the joining slope between the formation of Napo and Mera, in the slope of Pastaza river, and into the deposit. These sample were registered in files and coded each. Once the samples were taken in the field, the mineral, chemical and geo mechanical testing of the deposit was carried out, the geochemical test was performed in the laboratory of SECEMIN from University of Cuenca. The geo mechanical essays were performed at the MTOP laboratory from Morona Santiago. The calculation of the supplies was performed by means of the method of profiles, in this, 5 profiles were obtained at 200 meters from each other, having a total of 357´043.992 tons of verified reserves and 1´162.048,5 cubic meters of overload. Key words Limestone deposit – outcrop – deposits – geological profiles – verified reserves – overload – supply estimations.
