Describe folding on the map and identify the type of fault with reason(s).

Step 1: Match symbols to rock types from the legend.

Granite (A): speckled or dotted pattern.

Gneiss (B): foliated or wavy parallel lines pattern.

Massive limestone (C): uniform shading, no internal structure.

Dykes: narrow, straight intrusive bands cutting across other rocks.

Label regions on the map accordingly:

• Speckled areas → A

• Wavy foliated areas → B

• Uniform areas → C

• Thin cross-cutting bands → Dykes

Step 2: Identify types of structures (folds) with symbols on the map.

The map shows strike-dip lines curving around fold axes.

Anticline: convex upward, dips away from axis $\curvearrowright \curvearrowleft$ on limbs.

Syncline: concave upward, dips toward axis $\curvearrowleft \curvearrowright$ on limbs.

The two types of folds are anticline and syncline.
