基本解释

Cuttings are distinct from cavings, rock debris that spalls as a result of wellbore instability.

Because ice restricted to high altitudes and to polar regions, running water moves far more rock debris each year than ice does.
由于冰只局限在高地和极区，所以每年流水搬运的岩屑比冰所运走的多得多。
The fractal theory is applied to interpret the fracturing mechanism of rock debris which is analysed by the drillability energy test methods.
将分形理论用于解释岩石可钻性能量测试方法中岩屑试样的破碎机理。

岩屑
Composition——the guartz content in lower J1z is higher than the sandstones of T3x6,but its chert and metamorphic rock debris are apparently lower than the later;Texture maturity——J1z siltstone is much worse-sorted than the T3xv6 sandstone,the thin turbidites in J1z are not seen in T3x successions.
成分——J1z下部粉砂岩石英含量高于T3x6砂岩,而燧石和变质岩屑显著低于后者。结构成熟度——J1z粉砂岩分选程度显著低于T3x6砂岩,J1z中的薄层浊积是T3x中见不到的。
