3.1. the coarser constituents have points of
contact (not necessary visible in the plane of the section): close porphyricKEY TO C/F-RELATED DISTRIBUTIONS
Definition: the c/f related
distribution expresses the distribution of individual particles in relation
to finer material and associated voids not included in the particles (Stoops
& Jongerius, 1975)
1. only non-accommodating constituents larger than a postulated size limit are present: coarse monic
2. only constituents smaller than a postulated size limit are present: fine monic
3. the finer material fills all interstitial spaces between the coarser constituents: porphyric
3.1. the coarser constituents have points of
contact (not necessary visible in the plane of the section): close porphyric
3.2. the coarser constituents do not tough each
other, and their distance is
3.2.1. less than their mean diameter: single spaced porphyric
3.2.2. more than once, but maximum twice the mean diameter: double spaced porphyric
3.2.3. more than twice the mean diameter: open porphyric
4. both finer and coarser components and associated voids are present:
4.1. the finer material occurs as distinct aggregates
in the intergranular spaces between the coarser components: enaulic
4.2. the finer material occurs only as coatings
surrounding wholly or partially the coarser components: chitonic
4.3. the finer material occurs both as coatings
surrounding wholly or partially the coarser constituents and as concave bridges
linking the coarser constituents: chito-gefuric
4.4. the finer material occurs only as bridges
linking the coarser constituents: gefuric
4.4.1. the bridges are concave : concave gefuric
4.4.2. the bridges are convex : convex gefuric
5. others: complex intergrades (indicate them).
Note: for intergrades and mixtures of c/f-related distributions use the terminology as proposed by Stoops and Jongerius (1975).
