Definition of druse in English:

druse

noun druːzdruz

1Geology
A rock cavity lined with a crust of projecting crystals.
〔地质〕晶洞
1. 1.1 The crust of crystals lining a druse.
  晶簇
  Example sentencesExamples
  It generally occurs as crystalline druses on chalcopyrite, tetrahedrite, and other minerals and is sometimes associated with polybasite and dyscrasite.
  The crystals form druses that line the pockets and partially coat the copper crystal groups.
  Most such specimens are partially coated with a druse of calcite, epidote, and small, clear needle quartz crystals.
  Like the malachite, it occurs as druses that are perpendicularly attached to columns of gypsum.
  The contact between these zones is marked by large voids, the bottom surfaces of which are encrusted with druses of tabular microcline crystals.
2Botany
A rounded cluster of calcium oxalate crystals found in some plant cells.
〔植〕晶簇
Example sentencesExamples
- Considerable quantities of calcium oxalate druses were found in the leaves.
- Occasionally, calcium oxalate raphide or druse crystals were observed in this tissue.
- Some diagnostic features can be easily mistaken for others: short hairs for prickles, small glands and druses for papillae, etc.

Derivatives

drusy

adjective ˈdruːziˈdruzi

Geology

(of a rock cavity or surface) lined with a crust of projecting crystals.
〔地质〕晶洞
a drusy cavity of a green mineral
Example sentencesExamples
- The only consistently correct identifications were those made when distinct crystals could be seen or when the apple-green spheres were compact, with their outer surface smooth or only slightly drusy.
- They are brown in color, are usually encrusted with drusy quartz crystals, and reach lengths of 6 cm or more.
- To top it off, some of the quartz crystal vugs contain translucent pseudocubic crystals of calcite, to 1.2 cm on edge, perched on the drusy quartz.

Origin

Early 19th century: via French from German Druse 'weathered ore'.
