Question:
Which of the following is the fundamental constituent of humic coal?
Which of the following is the fundamental constituent of humic coal?
Show Hint
Macera is the key organic material in humic coal, responsible for its coalification process.
Updated On: Dec 11, 2025
- Mineral matter
- Maceral
- Lithotype
- Kerogen
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding Coal Composition.
Humic coal consists mainly of organic material that has undergone varying degrees of coalification. The primary constituent is the maceral, which is the organic portion of the coal.
Step 2: Analyzing the options.
(A) Mineral matter: Incorrect — Mineral matter is the inorganic material found in coal but is not the primary constituent of humic coal.
(B) Maceral: Correct — Macerals are the fundamental organic constituents of humic coal.
(C) Lithotype: Incorrect — Lithotype refers to the appearance or classification of coal based on its texture and composition, not a fundamental constituent.
(D) Kerogen: Incorrect — Kerogen is a precursor to oil and gas formation, not the main constituent of humic coal.
Step 3: Conclusion.
The correct answer is (B) Maceral, as it is the primary organic constituent of humic coal.
