Laitakarite, lanarkite, langite, laumontite, launayite, lawrencite, lazulite, lazurite, lead, lepidocrocite, leucite, libethenite, lillianite, linarite, lindströmite, linnaeite, liroconite, lithiophorite, lizardite, löllingite, luanheite, ludjibaite.
Launayite CuPb₁₀(Sb,As)₁₃S₃₀ mon.
Index of occurence in Slovakia: 1	Identification rating of mineral in Slovakia: 28
Type locality: Taylor Pit, Madoc, Huntingdon Township, Ontario, Canada (Jambor, 1967)
Oldest description from Slovakia area: Dúbrava (Adamus et al., 1993)
Localities in Slovak Republic (1) and identification rating (in parenthesis): Dúbrava - Ľubelská (2)
Size: macroscopic
Largest crystal from Slovakia area: 3 mm (Dúbrava; Adamus et al., 1993)
Picture (from SCAN) is in article of Adamus et al. (1993)

Notes: Adamus et al. (1993) have made XRD powder analysis of needles Pb-Sb sulphosalt from Dúbrava which probably correspond with launayite. Their microprobe analysis (no specification this analysis; total is 100.01 wt.%) is no launayite but probably dadsonite (authors don´t analyzed of chlorine) or other Pb-Sb sulphosalt. Moreover according to latest data, launayite contain Cu and As and launayite from Dúbrava contain only 0.27 wt.% As (Cu not analyzed).

Luanheite Ag₃Hg hex.
Index of occurence in Slovakia: 1	Identification rating of mineral in Slovakia: 28
Type locality: Luanheite occurence, Luan river (Luan He) Valley, Pref. Chengde, Prov. Hebei, China (Shao et al., 1984)
Oldest description from Slovakia area: Košice - Bankov (Peterec et al., 1993)
Localities in Slovak Republic (2) and identification rating (in parenthesis): Košice - Bankov (2), Novoveská Huta (2)
Size: macroscopic
Largest crystal from Slovakia area: - (unknown size of crystals)
Picture from electron microprobe (BEI) is in article of Háber et al. (1993)

Notes: From territory of Slovak Republic are known some mostly older descriptions of amalgam of silver of which some can probably be luanheite (e. g. from Nižná Slaná).

Index of occurence in Slovakia: 1. EXCEPTIONAL 1 - 2 localities 2. RARE 3 - 6 localities 3. INFREQUENT 7 - 15 localities 4. ABUDANT 15 - 50 localities 5. MORE ABUDANT > 50 localities

Identification rating of mineral in Slovakia: 1. WELL IDENTIFIED - mostly combination at least 2 most distinguished analytical methods (X -ray diffraction and electron microprobe) 2. PARTIALLY-INDENTIFIED - mineral mostly analyzed, but for well identification is need to make another analyses 3. UNDERIDENTIFIED - mineral mostly identified only visual, often very problematic or fictive
