Rhizoliths are organosedimentary structures formed in soils or fossil soils (paleosols) by plant roots. They include root moulds, casts, and tubules, root petrifactions, and rhizocretions. Rhizoliths, and other distinctive modifications of carbonate soil texture by plant roots, are important for identifying paleosols in the post-Silurian geologic record. Rock units whose structure and fabric were established largely by the activity of plant roots are called rhizolites.

| - تتكون الجذور الحجرية (Rhizoliths) عن طريق نقل الكالسيوم2+ والبيكربونات3- الذائبة، مما يعزز من ترسيب كربونات الكالسيوم3 في قطر يصل لعدة سنتيمترات حول الجذور. ويشيع تكون الجذور الحجرية في الترسبات الكلسية التي تتميز بوجود كميات هائلة من الكالسيوم2+ في نطاق الجذور ومن الممكن أن تؤدي إلى تكون قشرة قاسية حول الجذور يطلق عليها جذور حجرية.
