Crustal structure of the Borderland-Continent Transition Zone of southern California adjacent to Los Angeles [PDF]

open access: yes, 2003
We use data from the onshore-offshore component of Los Angeles Region Seismic Experiment (LARSE) to model the broad-scale features of the midcrust to upper mantle beneath a north-south transect that spans the continental borderland in the Los Angeles ...

Millennial storage of near-Moho magma [PDF]

open access: yesScience, 2019
Millennial magma reserves Lava erupts after being stored as magma deeper underground. Silica-rich magmas characteristic of volcanoes like Pinatubo are stored for thousands to hundreds of thousands of years. However, we have little understanding of the time scales for deeper basaltic magma like that supplying Icelandic volcanoes ...

The clashing of in situ and pre‐cast technologies—Western trends and local traditions in concrete engineering shaping shell construction in 20th‐century Hungary

open access: yesStructural Concrete, EarlyView.
Abstract After a blossoming pre‐World War II (WWII) period, the concrete construction industry in then‐socialist Hungary existed in a relative isolation from the Western World during the mid‐20th century. In this paper, we focus on the body of work of one of the then newly established state‐owned design offices, IPARTERV, to show how the isolation ...

Droughts and human impact in the ancient Uaymil region of the Maya lowlands inferred from a 2800‐year sedimentary archive at Lake Kaná, Mexico

open access: yesBoreas, EarlyView.
The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

The lithospheric mantle and lower crust-mantle relationships under Scotland: a xenolithic perspective [PDF]

open access: yes, 2011
In the British Isles the majority of volcanic rocks containing upper mantle and lower crustal xenoliths occur in Scotland. Most of the occurrences are of Carboniferous–Permian age.

A seismic model for crustal structure in North China Craton

open access: yesEarth and Planetary Physics, 2017
We present a digital crustal model in North China Craton (NCC). The construction of crustal model is based on digitization of original seismic sounding profiles, and new results of three-dimensional structure images of receiver functions.

The Bauhaus as Education Model: Enduring Design and Powerful Knowledge

open access: yesInternational Journal of Art &Design Education, EarlyView.
Abstract The influence of the Bauhaus art, design, and architecture school is still relevant a century after it was closed down. Although its theory of learning is somewhat elusive there is significant agreement that the school continues to inspire domestic and commercial design, as well as stimulating interdisciplinary learning in institutions across ...

Recognition and reconstruction of coherent energy with application to deep seismic reflection data [PDF]

open access: yes, 2000
Reflections in deep seismic reflection data tend to be visible on only a limited number of traces in a common midpoint gather. To prevent stack degeneration, any noncoherent reflection energy has to be removed.

Determining the Moho topography using an improved inversion algorithm: a case study from the South China Sea

open access: yesFrontiers in Earth Science
The Parker-Oldenburg method, as a classical frequency-domain algorithm, has been widely used in Moho topographic inversion. The method has two indispensable hyperparameters, which are the Moho density contrast and the average Moho depth.
