The invention relates to synthetic hybrid rock compositions, articles of manufacture and related processes employing mineral waste starting materials such as mine tailings, mine development rock, ash, slag, quarry fines, and slimes, to produce valuable articles of manufacture and products, which are characterized by superior physical and structural characteristics, including low porosity, low absorption, increased strength and durability, and retained plasticity. The resulting materials are compositionally and chemically distinct from conventional synthetic rock materials as demonstrated by scanning electron microprobe analysis, and are useful in a wide variety of applications, particularly with respect to commercial and residential construction.

We claim: 1. A composition comprising: a clast phase stock; a glass phase derived from melting of at least a portion of a primary mineral grain; and a plurality of distinct secondary crystalline phases in the glass phase, wherein the secondary crystalline phases comprise at least two distinct pyroxene phases, anhydrite and ilmanite. 2. A composition comprising: a clast phase comprising dissolved remnant of at least a portion of primary grains of a metavolcanic mine development rock; a glass phase derived from melting of at least a portion of a primary mineral grain; and a secondary crystalline phase comprising a crystallite in the glass phase, wherein the crystallite comprises anhydrite. 3. The composition of claim 2, wherein the crystalline phase comprises clusters of crystallites. 4. A composition comprising: a clast phase comprising dissolved remnant of at least a portion of primary grains of a fly ash; a glass phase derived from melting of at least a portion of a primary mineral grain; and at least three types of secondary crystalline phases comprising a crystallite in the glass phase, wherein the crystallite comprises anhydrite. 5. The composition of claim 1, wherein the composition is formed from mine tailings, or silicate waste materials selected from the group consisting of mine development rock, fly ash, bottom ash, slag, quarry fines, slimes, and combinations thereof. 6. The composition of claim 1, wherein at least a portion of said crystallite is selected from the group consisting of pyroxene, plagioclase feldspar, wollastonite, a sulfate mineral, enstatite, bronzite, hypersthene, augite, diopside, pigeonite, plagioclase, anhydrite, maghemite, ilmanite, rutile, cordierite and combinations thereof, optionally wherein said crystallite has lath morphological characteristics or equant blocky morphological characteristics. 7. The composition of claim 1, wherein said clast phase is crystalline or noncrystalline, wherein said crystalline clast phase is monomineralic or polymineralic. 8. The composition of claim 1, wherein said clast phase comprises a material selected from the group consisting of quartz, plagioclase feldspar, pyroxene, degraded chlorite, sphene, hematite, mineraloid grain, glass spherule, and combinations thereof. 9. The composition of claim 1, wherein said glass phase is heterogeneous and comprises aluminum, silicon, and lesser concentrations of cations, optionally wherein said cations comprise potassium, calcium, sodium, magnesium, or iron. 10. The composition of claim 1, wherein the composition has a water absorption of less than 7%. 11. The composition of claim 1, wherein the amount of the glass phase is less than 20 weight percent of the composition. 12. The composition of claim 1, wherein the composition is substantially impermeable, optionally wherein the composition is substantially impermeable without glazing. 13. The composition of claim 1, wherein the composition contains substantially zero open porosity, optionally containing closed pores. 14. The composition of claim 1, wherein a combination of the glass phase and the crystallite has a morphology that exhibiting that the crystallite is co-formed with the glass phase. 15. The composition of claim 2, wherein the composition is formed from mine tailings, or silicate waste materials selected from the group consisting of mine development rock, fly ash, bottom ash, slag, quarry fines, slimes, and combinations thereof. 16. The composition of claim 2, wherein at least a portion of said crystallite is selected from the group consisting of pyroxene, plagioclase feldspar, wollastonite, a sulfate mineral, enstatite, bronzite, hypersthene, augite, diopside, pigeonite, plagioclase, anhydrite, maghemite, ilmanite, rutile, cordierite and combinations thereof, optionally wherein said crystallite has lath morphological characteristics or equant blocky morphological characteristics. 17. The composition of claim 2, wherein said clast phase is crystalline or noncrystalline, wherein said crystalline clast phase is monomineralic or polymineralic. 18. The composition of claim 2, wherein said clast phase comprises a material selected from the group consisting of quartz, plagioclase feldspar, pyroxene, degraded chlorite, sphene, hematite, mineraloid grain, glass spherule, and combinations thereof. 19. The composition of claim 2, wherein said glass phase is heterogeneous and comprises aluminum, silicon, and lesser concentrations of cations, optionally wherein said cations comprise potassium, calcium, sodium, magnesium, or iron. 20. The composition of claim 2, wherein the clast phase has rounded edges resulting from dissolution of formerly angular grain boundaries. 21. The composition of claim 2, wherein secondary crystalline phase comprises crystallites having at least two distinct morphologies. 22. The composition of claim 4, wherein the composition is formed from mine tailings, or silicate waste materials selected from the group consisting of mine development rock, fly ash, bottom ash, slag, quarry fines, slimes, and combinations thereof. 23. The composition of claim 4, wherein at least a portion of said crystallite is selected from the group consisting of pyroxene, plagioclase feldspar, wollastonite, a sulfate mineral, enstatite, bronzite, hypersthene, augite, diopside, pigeonite, plagioclase, anhydrite, maghemite, ilmanite, rutile, cordierite and combinations thereof, optionally wherein said crystallite has lath morphological characteristics or equant blocky morphological characteristics. 24. The composition of claim 4, wherein said clast phase is crystalline or noncrystalline, wherein said crystalline clast phase is monomineralic or polymineralic. 25. The composition of claim 4, wherein said clast phase comprises a material selected from the group consisting of quartz, plagioclase feldspar, pyroxene, degraded chlorite, sphene, hematite, mineraloid grain, glass spherule, and combinations thereof. 26. The composition of claim 4, wherein said glass phase is heterogeneous and comprises aluminum, silicon, and lesser concentrations of cations, optionally wherein said cations comprise potassium, calcium, sodium, magnesium, or iron. 27.
