There are many surprises when applied to the discussion of natural occurrences. A modified classification of ele- ments based on basic chemical properties and their occurrences. A modified classification of elements based on basic chemical properties and their occurrences in nature is, therefore, proposed for students learning geochemistry and geologists working in the field. Elements are classified into six groups including lithophile, oxyphile, siderophile, chalcophile, biophile, and at- mophile elements. Five terms are taken from Goldshcmidt’s original classification. Oxyphile is a new term.展开更多

Oncocytoma refers to the tumour that is composed of oncocytes. Oncocytoma can occur in various organs throughout the body, commonly salivary glands, thyroid or kidney and less commonly in lung, parathyroid gland, ovary or pituitary gland.
