A metallic bond
Iron is a mineral, calcium and phosphorus are generally considered salts (though salts are also minerals).
Vermiculite is generally classified as a phyllosilicate which expands when heated. These are hydrated minerals that are composed of sheets of silicate tetrahedra.
A geode +++ Not quite. A geode is a crystalline feature, but the crystalline rocks are generally the igneous ones, and minerals.
