U široj okolici Zavižana na sjevernom Velebitu, S. Bertović je (1975) opisao smrekovu asocijaciju sa šarenkastom šašuljicom (Calamagrostio variae-Piceetum dinaricum Bertović 1975). Naziv je ...asocijacije nelegitiman (čl. 31. i 34a, Međunarodni kodeks fitocenološke nomenklature /ICPN/, Weber, Moravec i Theurillat 2000) pa je u radu naziv promijenjen u Hyperico grisebachii-Piceetum abietis (Bertović 1975) nom. nov. hoc loco i tako nomenkaturno revidiran. Osim toga, fitocenoza je istražena na širem području Dinarida u Hrvatskoj te uspoređena sa srodnim smrekovim zajednicama subalpskoga pojasa, uz određivanje dijagnostički važnih vrsta.
U članku su prikazani osnovni geološki, petrološki, geokemijski i rudnoležišni podaci za pet glavnih magmatsko-metalogenetskih formacija sjeverozapadnih i središnjih Dinarida: (1) permo-trijaske ...andezit-sko-diuritske riftne formacije; (2) jursko-donjokredne akrecione (ofiolitske) formacije; (3) gornjokredno-paleogene subdukcijske bazalt-riolitne formacije; (4) paleogene kolizijske granitne formacije, i (5) oligocensko-neogene postsubdukcijske andezitske formacije.
Sve te magmatsko-metalogene formacije stvarane su u različitim geotektonskim ambijentima za vrijeme alpinotipne evolucije dinarskih dijelova Tetisa i postorogene evolucije Paratetisa, odnosno bazena Panona.
Taložna evolucija eocenskog predgornog bazena Vanjskih Dinarida u sjevernoj Dalmaciji započinje karbonatnom sedimentacijom na predgornoj rampi, koja se povlačila. Klastična sedimentacija počinje s ...ranim ili fliškim stadijem, koji je predstavljen distalnim, prodeltnim pješčanim režnjevima s pridruženim hemipelagitima, koji su vezani za orogen i hranjeni rijekama. Naredni stadij punjenja odražava se u oplićavanju, koje je izazvala progradacija proksimalne prodelte. Slijedi taloženje ispred delti pletenih ravnica ili pletenih delti, što je vjerojatni nastavak stadija punjenja ili možda upućuje na stabilno stanje (ispunjeni stadij). Ovakva taložna evolucija može se usporediti s evolucijskim stilom, kakav je tipičan za periferne predgorne bazene, osobito one alpske domene, i usko je povezana s tektonskim razvitkom predgorja i orogena. Glavni procesi taloženja klastita bili su vezani za guste tokove niz dno, koji su nastajali iz poplava i proizlazili iz brojnih deltnih ušća. Ti tokovi mogli su biti utjecani oscilatornim tokovima. Odnosni riječni sliv označavala je snažna erozija u planinskim predjelima, što je bilo vezano za aktivnu kompresijsku tektoniku uzdizanog orogena i snažne tekućice.

Međusobni odnosi minerala i njihova kemija proučavani su u nekim bazičnim magmatskim stijenama ofiolitnog kompleksa Banije. Na temelju mineralnih i stukturnih karakteristika razlikuju se tri vrste ...stijena: metadijabazi I (karakterizirani sekundarnim amfibolom), metadijabazi II (karakterizirani sekundarnim albitom) i spilit. Dana je detaljna kemija svih mineralnih faza, osobito zoniranih klinopiroksena i zoniranih amfibola. Crne opâke faze sastoje se od različitih Fe-Ti-Mn oksida (ilmenit, Mn-ilmenit, magnetit, Ti-magnetit, Fe-pseudobrukit) koje su često na rubovima potisnute Al- i Fe-bogatim titanitom. Sve su stijene hidrotermalno metamorfozirane pri čemu je amfibol djelomično ili potpuno potisnuo klinopiroksen, a plagioklas je izmijenjen u albit, prehnit, pumpeliit i/ili sericit. Pojavljuje se također i sekundarni klorit. Ukupna kemijska analiza svake proučavane stijene odgovara toleitskom bazaltu.
The investigation of the high mountain flora in the Dinara, Troglav and Kamesnica, i. e. the central part of the chain of the Dinarides, was carried out to establish its origin and age. The study was ...restricted to the alpine associations within climatic region of the distribution of Pinus mugo and submountainous Fagus silvática forests; there is no timberline and the high mountain vegetation in this region is caused by local climate, orographic or anthropogenic conditions.
In the study the author brings out the results he obtained in trying to establish the main centres of development of the flora of the quoted Mountains and then its age. Some basic facts and data about the origin of the Dinara Mountains and about the general history of the flora of the wider area of the Balkan peninsula from the Tertiary are briefly stated. The stress is put on the general significance of palaeobotanical and particularly pallynologic research for the knowledge of florogenetic relations. In the absence of fossil proofs the plants classified according to their present actual spread on the earth and good knowledge of systematic phylogenetic relations of individual taxa were in this study the only real basis in determining the genesis of these flora elements.
Selected members of the mountain flora in the region were earlier examined in detail (Volarić-Mršić 1972) as regards their geographic distribution, phytocenological connection and phylogenetic relations
within the genus or section and their variability. Using the geographic systematic method and starting primarily from the flora geoelement whose classification was done earlier (Volarić-Mršić 1972) results of the research are: most of the plants investigated originate from the region of European mountain system (79 taxa), many have their origin in the Dinara Mountains (51 taxa, most of them belonging to the Dinaric geoelement), whilst 23 developed in South-eastern Europe. A small number (12) are from Central Asia and only one from America.
As to the age of the high mountain flora of the Dinara, Troglav and Kamesnica mountains, the author came to the conclusion that it consists mostly of autochthonous tertiary taxa, the additions from later periods being in minority. Also it is stressed that the history of the Dinara mountains flora might have started not before the main folding period of this mountain system, and one should bear in mind that the Dinara Mountains attained their final hight in the Pleistocene.
