Reijo Salminen, Editor of Geochemical Atlas of Northern Europe advised me once again, and Ms. Becky Bingham in Sandy, Utah got me and my wife interested about geology in Yellowstone.
Eelis Pulkkinen, discoverer of Pahtavaara gold ore was my co-working reconstructor of Sattasvaara cinder cone already in the 80s. We have Booth C11 "Kittilä supervolcano - A gold source in Archean mantle underplating" in FEM2017. Our goal is financial support to develop at least Sattasvaara volcano into target for international geo-tourism - and to locate the rest of the volcanic vents at the calderas of Kittilä supervolcano. Financing could mean the best goodwill to international prospectors in Lapland that contains much more mine possibilities than the prevailing theories can promise. The start was sponsored by K.H. Renlunds Stiftelse.

This website is collection of my
Synopsis "Komatiitic Explosive Volcanism, Volcanoes, and Its Tectonic
Significance in Northern Finland, the Fennoscandian (Baltic) Shield" for
academic dissertation which was unaccepted 1991 and 1992. The (unpublished)
abrichment is no-updated introduction to my manuscript "High viscosity
and cooling rate in komatiites: Extrusions from mantle underplating at ~ 2,7 Ga
in North Finland?" (
review, disclaimed 2015).
My investigation was actualized at the 2000's by Europe's biggest nickel-ore deposit
of AngloAmerican Ltd within
the mantle-plume area as a surprice in the framework of traditional
Proterozoic plate-tectonic models of North Finland. Metamorphic
evolution of the present-like komatiites made difficult to understand that
the rocks are Archaean in origin.
Dear Visitor, if you refer or referred to my investigation would you inform me of your interesting paper, please.
Enormous komatiitic explosions in large pyroclastic zone conjoined with shield-wide mantle diapir.
Magmatic explosions resulted from high viscosity of the komatiite lavas from differentiated ultramafic magma which cooled enough during its upwelling through thick continental crust.
Komatiite center with high gold potential is formed upon a mantle plume delineated by distinct gravimetric anomaly.
Convection-cell mechanism was feasible only under broken continental nuclei, where the liberated bottom-top convection initiated the cell mechanism because the free high-thermal energy only escaped from surrounding "oceanic" provinces.

Totuus Geologiassa. Abstract: Philosophical truth in the Geology
We must apply (geological) principles out of our
empirical knowledge to simplify the universe of discourse. David
asked about the competence of the principles applied to the scientific
discussion and John Locke was afraid of such people,
who have administrative law accompanied by a strong will to dictate the
competence of the principles. That was destiny of my career in the form of my
unaccepted academic dissertation 1991 in Helsinki University but also 1992 in Åbo
Akademi, its unpublished version 2008 for Bull. Geol. Soc. Finland, its
cancelled poster presentation in Geological Colloquium at Helsinki 2007 and its
unpublished brief note as a Finnish-English version 2010 in Society’s
newsletter Geologi. (But Aku Heinonen, editor of ‘Geologi’ accepted my brief
note at last to Geologi 4/2014.)
original (Finnish) justification for rejecting of my Synopsis i.e. summary of the published editions:
”Emme ole erityisemmin tarkastaneet kirjallisuusviitteitä, mutta… GTL:lla on ollut monivuotinen tutkimusprojekti selvittämässä Keski-Lapin vulkaanisia kiviä. Tällä projektilla on ollut aivan toisenlainen tutkimuskapasiteetti käytössään kuin Saverikolla. Siten osajulkaisujen tieteellinen merkitys on vähentynyt osin jo nyt ja vähenee edelleen huomattavasti, kun Lapin vulkaniittiprojektin loppuraportit ilmestyvät” (Prof. Kauko Laajoki & Dr. Ahti Silvennoinen, 1991).
Freely translated: We have not particularly audited the references, but ... GSF has studied many years volcanic rocks in central Lapland and has completely different capasity for research than that of Saverikko. That is why the scientific importance of the editions has declined in part already (at 1991), and will continue to decrease significantly when the report of the Lapland Volcanite Project is published. Report (75 Mb) = Report of Investigation 140, Geol. Surv. Finland, Espoo 1998).
cream on the cake my own Professor Ilmari Haapala did not do any markings
about the conclusion of my dissertation process (Jorma Äijö, Faculty Administrative
Manager, 2013) and denied anyone even to
have ordered to referees (Prof. Juha Karhu 2013). He said as supervisor of our
Finnish-Tanzanian project, that “Saverikko skims only the cream from the milk”
(Dr. Tapio Koljonen 1983-84).
Younger Finnish referees also deseased my later manuscripts from spreading into international and domestic discussion. My opinion was fenced out of Platon’s dialogue and Hegel’s dialecties. The methods form way of Leibniz’s sufficient argumentation and Descartes’s systematic scepticism, to bring into use a new explanation of higher scientific rate. Geological knowledge becomes actual on time from a group of potential explanations the all of which, after Aristoteles, stay in existence. Descartes does not accept authorities, traditions or routines for a base of the knowledge. Some of the highly graduated geologists in Finland do not understand the difference between actualization and authorization: the argument (or interpretation in geology) is not scientific, if it can not be disproved (Karl Popper). The dogmas belong under theology, and the dogmatism shows lack of courage (Nietsche).
But fortunately, Prof. Haapala was the only one who in the supervisory board of GSF repeatedly refused to hire me researcher (ex-Chief of GSF Kalevi Kauranne 1999). Otherwise, my career should be composed of studies like that of stratigraphic situation between the “Backyard Formation” and the “Front-yard Formation”.
