Feldspar
Definition:
(n.) Alt. of Feldspath
Example Sentences:

(10) Eighty-eight were of mineral origin, mainly quartz and feldspar, and it is believed that the great majority were submitted for secondary gain or for psychiatric reasons.
(11) Feldspar-alumina composites shrank approximately 30%; shrinkage of 15-20% occurred only in composites involving spherical alumina (average particle size 5.4 microns).
(12) Kaolinite, talc, mica, feldspars, and crystalline silica comprised the majority of particles of both groups.
(13) If the soil where potatoes are grown contains feldspars, sprout inhibition treatment with 100-200-Gy doses can also be detected for up to one year, using the 90-250 degrees C low-temperature part of the TL spectrum for evaluation.
(14) Composites of feldspar and spherical alumina were observed to be stronger than those of feldspar and nonspherical alumina.

(20) The degradability of DNA adsorbed to minor mineral fractions (feldspar and heavy minerals) of the sand differed from that of quartz-adsorbed DNA.
Norite
Definition:
(n.) A granular crystalline rock consisting essentially of a triclinic feldspar (as labradorite) and hypersthene.
Example Sentences:
(1) [35S]GTP gamma S bound to GTP-binding protein was assayed by repeated treatments with a Norit solution and centrifugation.
(2) 43.056-43.062), except that N-bromosuccinimide is used instead of Norit to oxidize vitamin C. Ascorbic acid is selectively oxidized by N-bromosuccinimide before other interfering substances that may be present, so this method is a highly sensitive and specific technique with extensive applicability.
