TABLE A.5
Fracture Density Descriptors

S

Descriptor Criteria
(Excludes Mechanical Breaks)
Unfractured No observed fractures.

Ve sli htl fractured Core recovered most) in len the realer than 3 feet 1 m .

Slight to very slightly
fractured'

Slightly fractured Core recovered mostly in lengths from 1 to 3 feet (300 to 1000 mm) with
few scattered lengths less than 1 foot (300 mm) or greater than 3 feet
1000 mm).

Moderately to slightly
fractured'

Moderately fractured Core recovered mostly in lengths from 0.33 to 1.0 foot (100 to 300 mm)
len the with most lengths about 0.67 foot (200 mm).

Intensely to
moderate) fractured'

Intensely fractured Lengths average from 0.1 to 0.33 foot (30 to 100 mm) with scattered
fragmented intervals. Core recovered mostly in lengths less than 0.33
foot 100 mm .

Very intensely to
intense) fractured`

Very intensely
fractured Core recovered mostly as chips and fragments with a few scattered short
core lengths.
`Combinations of fracture densities are permissible (e.g., very intensely to intensely fractured or moderately to
slightly fractured) where equal distribution of both fracture density characteristics are present over a significant
core interval or exposure, or where characteristics are "in between" the descriptor definitions.
