Question

Randomly oriented ore-bearing veinlets in a mass of rock are known as

• A. en echelon veins
• B. sheeted veins
• C. lode
• D. stockworks

Hint:

Stockworks are networks of intersecting veins or veinlets, commonly found in ore deposits.

Answer 1

The Correct Option is D

Step 1: Understanding Ore Vein Terminology.
Stockworks are networks of veins or veinlets that are randomly oriented and crosscut a rock mass. They typically represent zones of mineralization.

Step 2: Analyzing the options.
(A) en echelon veins: These veins are parallel and offset, forming a stepped pattern, not random.
(B) sheeted veins: These veins are parallel and closely spaced, typically oriented in the same direction.
(C) lode: A lode refers to a rich mineral deposit or vein, not a network of randomly oriented veins.
(D) stockworks: Correct — A stockwork is a network of veins, often mineralized, that crosscut each other in a random orientation.

Step 3: Conclusion.
The correct answer is (D) stockworks, as these represent a network of randomly oriented ore-bearing veinlets.
