I.- REGULAR MEETINGS

The SEG PUCP-UNSAAC Joint Student Chapter Meetings are carried out once a week and various types of plans are discussed, such as conferences, field trips, short courses, and future activities (fig. 1). Several general and specific topics of Geology are debated as well, for better understanding and learning. In addition, it is worth noting that a key point of this human group is the development of extracurricular activities, so an international visit was made by a group of Colombian students, members named “ Research Group Technominas” in September 2016 (figs. 2 and 3). Fraternization meetings with students from SGA-CUSCO during the current year (fig. 4), as well as internal talks and discussion inside the student chapter about geological topics (figs. 5 and 6) have been done.

V. RESEARCH

1. Title: “Stratiform Copper Deposits in the San Jeronimo Group, Cusco Area, Peru:

Petromineralogical and Genetic Case Study of the Tambomachay Deposit”

2. Authors: Carlos A. Salcedo, Marco Augusto Misael Robles, Silvia Rosas

3. Abstract:

Peru is currently the second largest copper producer in the world with a production of 2.3Mt mainly

contributed by porphyry systems. Exploration for and research on the porphyry ores are

considerable, but there is a lack of study of copper-bearing clastic sedimentary rocks as possible

sources for sedimentary rock-hosted stratiform copper deposits (SRHSCD).

Near Cusco, in the southeast of Peru, copper oxide ores were extracted in nine small-scale historic

mines. These deposits host stratiform copper orebodies within the Eocene-Oligocene San Jeronimo

Group. One of these deposits, developed by the Tambomachay mine, was chosen for detailed study.

The objective was to determine whether this could be classified as a SRHSCD. The methodology

included bibliographic research, field work, and petromineralogical and geochemical analyses.

A feldspathic greywacke of the San Jeronimo Group, varying from 10 to 90 cm in thickness, hosts ore

that is either disseminated predominantly along laminations or within veinlets. The primary minerals

are chalcopyrite and bornite, there is also abundant chalcocite, and covellite-digenite replaces

chalcocite. The presence of oxide minerals (malachite, brochantite, goethite) intergrown with the

ores, particularly with covellite, chalcocite, and digenite, suggests a supergene enrichment event.

Nevertheless, it is also possible that these oxides are of primary origin. The presence of calcite and

chlorite has been observed in veinlets, with the chlorite suggesting some involvement of

hydrothermal fluids. Six samples of the ore were analyzed for 50 elements analysis (ICP-MS) with

digestion by four acids. The results show enrichment in metals that include Ag, Pb, and Zn, as well as

in large ion lithophile elements that suggests the sedimentary rocks of the San Jeronimo Group were

derived from a source with calc-alkaline composition.

We preliminarily suggest that Tambomachay is a SRHSCD, based mainly on petromineralogical and

geochemical analyses. The basin architecture of the studied area is similar to the general basin model

that characterizes most SRHSCDs and this work suggests that the source of the sulfur could be the

evaporites of the Maras Formation. The texture, as well as the presence of chlorite and ore in veinlets,

rules against a previously hypothesized syngenetic ore model. To confirm the existence of

widespread SRHSCD occurrences, detailed geological and structural mapping, and fluid inclusion and

isotope geochemistry will be carried out on the nine known occurrences in the Cusco region.
