The most common 1:1 type of clay mineral in soil is-
The most common 1:1 type of clay mineral in soil is-
Show Hint
Kaolinite exhibits low cation exchange capacity (CEC) and non-expanding properties because the hydrogen bonds between adjacent sheets are exceptionally strong.
Updated On: Jul 10, 2026
- Montmorillonite
- Kaolinite
- Vermiculite
- Halloysite
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Silicate clays are structured sheet-like minerals composed of silicon-oxygen tetrahedral sheets and aluminum-hydroxyl octahedral sheets.
Step 2: Detailed Explanation:
- Kaolinite is a non-expanding silicate clay composed of alternating single tetrahedral and octahedral sheets (1:1 ratio). It is the most dominant and widespread 1:1 clay mineral found in highly weathered soils.
- Montmorillonite and Vermiculite are 2:1 type expanding clay minerals.
- Halloysite is a 1:1 type clay mineral, but it is less common and typically possesses a tubular structure.
Step 3: Final Answer:
Hence, the most common 1:1 type of clay mineral is Kaolinite.

- Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : Intense weathering of soil shifts its Zero Point Charge towards higher pH owing to greater accumulation of iron and aluminum oxides.
Reason (R) : The application of organic matter in soil also pushes the soil Zero Point Charge towards higher pH.
In light of the above statements, choose the most appropriate answer from the options given below. - Arrange the following in decreasing order according to the number of linkages among silicon tetrahedra of soil particles:
(A). Nesosilicates,
(B). Phyllosilicates,
(C). Tectosilicates,
(D). Inosilicates
