the Cajamarca region through the use of satellite images
and being able to perform the zoning of hydrothermal
alterations for the delimitation of possible exploratory tar-
gets, which would serve as a basis for future more detailed
studies carried out by mining companies for the prospect-
ing of new deposits and that in the future they will be used
for the extraction of mineral resources.
GEOLOGICAL SETTING
Regional Geological Setting
The study area, is located within Asuncion and Cospan dis-
tricts (Figure 1), in the southwest of the Cajamarca region,
whose geological formations belong to the Upper Lower
Cretaceous period and the granodiorite intrusives of the
Paleogene.
It is located in the Gold-Copper Belt of Northern Peru,
one of the belts that houses a significant number of deposits
and occurrences of gold, copper- gold.
Regionally, the Cajamarca region is mostly covered by
sedimentary rocks of the Cretaceous (Figure 2). It begins
with the Goyllarisquizga Group, whose outcrops are silico-
clastic environments, and consists of a sequence of siltstones,
claystones and quartz sandstones with a fine to medium
grain variation. Then the Inca Formation continues, which
consists of ferruginous sandstones, claystones and siltstones
with a yellowish-reddish color due to the presence of iron
in its strata. Overlying outcrops of carbonate rocks, such as
the Crisnejas Group Formations (Chulec and Pariatambo
Formations), the Pulluicana Group (Yumagual and
Mujarrún Formations) and the Cajamarca and Celendín
Formations. It also presents Quaternary deposits of fluvial,
glacial, lagoonal, colluvial and alluvial origin.
The Estructural Setting
In the study area is evidenced by Andean strike-slip faults
with a NW SE direction and Trans- Andean strike-slip
faults NE SW. In addition, based on the interpretation of
satellite images, some faults have been identified, some of
which present a left-lateral movement.
Chira et al. (2007) indicates that these faults present
evidence of four stages of deformation that began in the
late Cretaceous and continued during the Cenozoic, all
of them corresponding to the movements of the Andean
Cycle. These deformation phases are evidenced by uncon-
formities, folds and structures.
In the study area, is located in one of the main struc-
tural corridors that control the formation of deposits, is
called the Chicama – Yanacocha Structural Corridor.
The Chicama – Yanacocha structural corridor with a
strike-slip of N 40° E controls the succession of a series of
structural phenomena, magmatic and hydrothermal. Many
metallic deposits are aligned within this structural corridor
(Chira et al., 2007).
