'hornblende-laden' originates from English, specifically the compound 'hornblende' + 'laden', where 'hornblende' ultimately comes from German 'Hornblende' (from 'Horn' meaning 'horn' and 'Blende' meaning 'deceiver' as used in mineral names) and 'laden' comes from Old English/Germanic roots meaning 'to load' or 'to be full of'.

'hornblende' was borrowed into English from German 'Hornblende' in modern mineralogical usage; 'laden' is the past-participle/adjectival form related to Old English 'lādian'/'lǣdan' (to load) and Middle English 'laden'; the two elements were combined in modern English to describe rocks or materials 'laden' with hornblende.

Initially, the compound simply described something 'bearing or loaded with hornblende'; this basic sense has remained stable and is still used in geological descriptions.
