 Hambaek Syncline. This structure consists
of a thick sequence of sedimentary rocks of the Taebaek Series, composed of Cambro-Ordovician interlayered limestones, shales and quartzites
of the Joseon System. This sequence is unconformably overlying the Pre-Cambrian schist and gneiss basement of the Yulri Group of the
Yeongnam massif. The stratigraphy in the Sangdong area is mainly composed of the basal Jangsan quartzite, Myobong slate and the overlying
Pungchon limestone formations with Cambrian age, which belong to the Joseon Supergroup.

The tungsten mineralization
of the Sangdong deposit is contained in several tabular, bedding-conformable skarns in the Myobong Shale formation. The ore deposit is
strata-bound, with the strike and dip of the hosting formations. These skarns have been interpreted as comprising carbonate-bearing horizons
that were hydrothermally altered and mineralized by fluids ascending from the underlying Sangdong Granite.

From uppermost to
lowermost, the mineralized horizons are termed as Hangingwall, Main, and Footwall horizons, as shown in Figures 7-4 and 7-5 below. The
Footwall and Main horizons have thicknesses that typically range from 1 to 4 m. As well as the main mineralization on these beds, there
are often thin calc-silicate layers developed on the upper and lower contacts of the Main and Footwall horizons.

The Hangingwall horizon
is located near the upper contact of the Myobong shale and varies in thickness from approximately 5.0 to 30.0 m because of the irregular
boundary of the shale with the overlying Pungchon Limestone. This zone has a strike length of about 600 m and a down-dip extent of about
800 m. Above the most highly altered portion of the Main horizon, the Hangingwall horizon is not tabular, but extends steeply and irregularly
into the overlying limestone. The base of the Hangingwall horizon is approximately 14 m above the upper contact of the Main horizon.

The Main horizon
strikes about 100° and dips northerly between 15° and 30°. The strike length is in excess of 1,300 m and thickness varies
from 5.0–6.0 m. Hydro
